Installing .NET SDK on Ubuntu 20.04 with the commands listed in the Install .NET on Ubuntu docs:
wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
rm packages-microsoft-prod.deb
sudo apt-get update; \
sudo apt-get install -y apt-transport-https && \
sudo apt-get update && \
sudo apt-get install -y dotnet-sdk-6.0
produces no dotnet executable.
Command 'dotnet' not found, but can be installed with:
sudo snap install dotnet-sdk
Listing files from the package:
dpkg -L dotnet-sdk-6.0 | grep -P "dotnet$"
gives
/usr/share/dotnet
The /usr/share/dotnet directory contains no executable. I compared this result with my other Ubuntu installation where I installed dotnet ages ago, and there it is installed in /usr/share/dotnet but there exists a /usr/share/dotnet/dotnet executable.
What am I doing wrong? How to install dotnet on Ubuntu with APT?
Using snap is not an option.
sudo apt reinstall dotnet-host and then sudo apt install dotnet-sdk-6.0 fixed the issue.
See: https://github.com/dotnet/installer/issues/12939
dpkg -S /usr/bin/dotnet says that it was created by dotnet-host.
So maybe that package is missing in dotnet-sdk-6.0 and must be installed separately. I imagine they will fix it in some future version.
tl;dr $ sudo apt install dotnet-host
I'm trying to install the .Net 5 Runtime on Armbian Focal (Ubuntu 20.04) or Buster (Debian 10), running on an Orange Pi Zero.
So I followed Microsoft's instructions here:
https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu
but on the last step:
sudo apt-get install -y aspnetcore-runtime-5.0
I get this error:
E: Unable to locate package aspnetcore-runtime-5.0
E: Couldn't find any package by glob 'aspnetcore-runtime-5.0'
E: Couldn't find any package by regex 'aspnetcore-runtime-5.0'
I then followed Microsoft's suggestion for installing it manually from here:
https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu#apt-troubleshooting
But on the last step, again I get the same error.
Any ideas?
In summary, these are the steps I tried first:
wget https://packages.microsoft.com/config/ubuntu/20.10/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update; \
sudo apt-get install -y apt-transport-https && \
sudo apt-get update && \
sudo apt-get install -y aspnetcore-runtime-5.0
and these are the steps I tried when the above failed:
sudo dpkg --purge packages-microsoft-prod && sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update
sudo apt-get install -y gpg
wget -O - https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor -o microsoft.asc.gpg
sudo mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/
wget https://packages.microsoft.com/config/ubuntu/{os-version}/prod.list
sudo mv prod.list /etc/apt/sources.list.d/microsoft-prod.list
sudo chown root:root /etc/apt/trusted.gpg.d/microsoft.asc.gpg
sudo chown root:root /etc/apt/sources.list.d/microsoft-prod.list
sudo apt-get update; \
sudo apt-get install -y apt-transport-https && \
sudo apt-get update && \
sudo apt-get install -y aspnetcore-runtime-5.0
EDIT:
I've previously installed the .Net Core 3.1 Runtime on this exact same setup without any issues. I'm not sure if there is something in .Net 5 that is different which won't allow me to install it
From the first URL you linked: https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu
Package manager installs are only supported on the x64 architecture. Other architectures, such as ARM, must install .NET by some other means such as with Snap, an installer script, or through a manual binary installation.
A Pi is an ARM device, so the installation method you are trying to use is not supported.
I have an already compiled Linux app which has become dated. To use it, I want to create a Docker image and an appropriate environment to work with. My problem is that is app requires an older version of the boost libraries. 1.57.0 to be specific.
I have been able to get boost installed (I believe correctly) but the app errors out.
The error that I am getting is:
undefined symbol: _ZN5boost15program_options3argE
I am hoping someone has experience with this. Briefly, my pipeline is:
get the rocker/verse Docker image that has Debian and R and some more goodies I need.
Bash in to it, apt-get install ... etc.
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install build-essential g++ python-dev autotools-dev libicu-dev build-essential libbz2-dev libboost-all-dev
cd home
wget -O boost_1_57_0.tar.gz https://sourceforge.net/projects/boost/files/boost/1.57.0/boost_1_57_0.tar.gz/download

./b2 toolset=gcc cxxflags=-std=gnu++0x

I would like to compile / configure Caffe so that when I trained an artificial neural network with it, the training is multi-threaded (CPU only, no GPU). How to enable multithreading with Caffe? I use Caffe on Ubuntu 14.04 LTS x64.
One way is to use OpenBLAS instead of the default ATLAS. To do so,
sudo apt-get install -y libopenblas-dev
Before compiling Caffe, edit Makefile.config, replace BLAS := atlas by BLAS := open
After compiling Caffe, running export OPENBLAS_NUM_THREADS=4 will cause Caffe to use 4 cores.
If interested, here is a script to install Caffe and pycaffe on a new Ubuntu 14.04 LTS x64 or Ubuntu 14.10 x64. CPU only, multi-threaded Caffe. It can probably be improved, but it's good enough for me for now:
# This script installs Caffe and pycaffe on Ubuntu 14.04 x64 or 14.10 x64. CPU only, multi-threaded Caffe.
# Usage:
# 0. Set up here how many cores you want to use during the installation:
# By default Caffe will use all these cores.
NUMBER_OF_CORES=4
# 1. Execute this script, e.g. "bash compile_caffe_ubuntu_14.04.sh" (~30 to 60 minutes on a new Ubuntu).
# 2. Open a new shell (or run "source ~/.bash_profile"). You're done. You can try
# running "import caffe" from the Python interpreter to test.

I have placed this script on GitHub: https://github.com/Franck-Dernoncourt/caffe_demos/tree/master/caffe_installation .
This is to just extend Franck's answer where he used sed to modify the config file. If you are having problems with that, here is another way to get the same thing done.
The difference is that instead of changing the config file you directly change the camke flag cmake -DCPU_ONLY=1 -DBLAS=open ..
$sudo apt update && sudo apt-get install -y libopenblas-dev
$git clone -b 1.0 --depth 1 https://github.com/BVLC/caffe.git . && \
pip install --upgrade pip && \
cd python && pip install -r requirements.txt && cd .. && \
mkdir build && cd build && \
cmake -DCPU_ONLY=1 -DBLAS=open .. && \
make -j"$(nproc)"
While building caffe, you have to add the -fopenmp to the CXXFLAGS and LINKFLAGS to support OPENMP. If you have a flag named OPENMP in the Makefil.config, you can simply set that to 1. You can use either OPENBLAS or Intel MKL BLAS library. While building the OPENBLAS you need to set USE_OPENMP=1 flag so that it supports OPENMP. After building caffe, please export the number of threads you want to use during runtime by setting up OMP_NUM_THREADS=n where n is the number of threads you want. Here is a good discussion related to multi-threading in Caffe: https://github.com/BVLC/caffe/pull/439
I set up PhantomJS and recorded it to video: https://www.dailymotion.com/video/xnizmh_1_webcam
Build instructions: http://phantomjs.org/build.html
Is there anything wrong in my setup?
After I set it up I read the quick start tutorial and tried to write this code
phantomjs hello.js
It gives me "command not found" error. How can I solve this problem?
Guidouil's answer put me on the right track. I had to add one additional symlink to /usr/bin/, and I did direct symlinks for all 3 - see below.
I'm installing on Ubuntu server Natty Narwhal.
This is exactly what I did.
cd /usr/local/share
sudo wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.7-linux-x86_64.tar.bz2
sudo tar xjf phantomjs-1.9.7-linux-x86_64.tar.bz2
sudo ln -s /usr/local/share/phantomjs-1.9.7-linux-x86_64/bin/phantomjs /usr/local/share/phantomjs
sudo ln -s /usr/local/share/phantomjs-1.9.7-linux-x86_64/bin/phantomjs /usr/local/bin/phantomjs
sudo ln -s /usr/local/share/phantomjs-1.9.7-linux-x86_64/bin/phantomjs /usr/bin/phantomjs
And finally when I do
phantomjs -v
I get 1.9.7
If anyone sees any problems with what I've done, please let me know.
PhantomJS is on npm. You can run this command to install it globally:
npm install -g phantomjs-prebuilt
phantomjs -v should return 2.1.1
download from phantomjs website the prebuilt package :
http://phantomjs.org/download.html
then open a terminal and go to the Downloads folder
sudo mv phantomjs-1.8.1-linux-x86_64.tar.bz2 /usr/local/share/.
cd /usr/local/share/
sudo tar xjf phantomjs-1.8.1-linux-x86_64.tar.bz2
sudo ln -s /usr/local/share/phantomjs-1.8.1-linux-x86_64 /usr/local/share/phantomjs
sudo ln -s /usr/local/share/phantomjs/bin/phantomjs /usr/local/bin/phantomjs
then to check install phantomjs -v should return 1.8.1
Install from package manager:
sudo apt-get install phantomjs
Here are the build steps I used (note these instructions are for version 1.3. See comments to this answer for the installation instructions of the latest PhantomJS):
sudo apt-get update
sudo apt-get install git-core
sudo apt-get install build-essential
sudo apt-get install libqt4-dev libqtwebkit-dev qt4-qmake
git clone git://github.com/ariya/phantomjs.git && cd phantomjs
git checkout 1.3
qmake-qt4 && make
Now install Xvfb
sudo apt-get install xvfb xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic
Launch Xvfb:
Xvfb :23 -screen 0 1024x768x24 &
Now run phantom:
DISPLAY=:23 ./phantomjs hello.js
For PhantomJS version above 1.5, consider this (verbatim copy of the build instructions on the phantom website):
For Ubuntu Linux (tested on a barebone install of Ubuntu 10.04 Lucid
Lynx and Ubuntu 11.04 Natty Narwhal):
sudo apt-get install build-essential chrpath git-core libssl-dev libfontconfig1-dev
git clone git://github.com/ariya/phantomjs.git
cd phantomjs
git checkout 1.7
./build.sh
For Ubuntu you can use the prebuilt versions downloadable from the PhantomJS site.
If you have some serious time on your hands you can also build it yourself. (This is exactly the procedure from Nikhil's answer).
The guys over at PhantomJS recommend using the binaries to save time:
Warning: Compiling PhantomJS from source takes a long time, mainly due to thousands of files in the WebKit module. With 4 parallel compile jobs on a modern machine, the entire process takes roughly 30 minutes. It is highly recommended to download and install the ready-made binary package if it is available.
With a modern machine they mean > 4 cores, > 8gb mem I think. I tried it on a micro AWS instance and gave up after 2 hours.
In short: install the prebuilt packages from the PhantomJS site per their instructions.
Personaly I prefer using npm (see Arnel Bucio answer)
sudo npm install -g phantomjs
but! I noticed that some of npm module still can't see it as global executable.
so!
Create new /usr/share/phantomjs/ directory link
cd /usr/share
sudo ln -s ../lib/node_modules/phantomjs/lib/phantom phantomjs
Remove old /usr/bin/phantomjs executable link and create the new one
cd /usr/bin
sudo mv phantomjs phantomjs.old
sudo ln -s ../share/phantomjs .
in my vagrant bootstrap:
apt-get install -y build-essential chrpath git-core libssl-dev libfontconfig1-dev
git clone git://github.com/ariya/phantomjs.git
cd phantomjs
git checkout 1.9
echo y | ./build.sh
ln -s /home/vagrant/phantomjs/bin/phantomjs /usr/local/bin/phantomjs
cd ..
I have done with this.
sudo apt-get update
sudo apt-get install build-essential chrpath git-core libssl-dev libfontconfig1-dev
git clone git://github.com/ariya/phantomjs.git
cd phantomjs
git checkout 1.9
./build.sh
See link
Installation guide is in ...
https://gist.github.com/julionc/7476620
And run in terminal with this command
phantomjs --webdriver=4444
From the official site: phantomjs site
sudo apt-get install build-essential chrpath git-core libssl-dev libfontconfig1-dev
git clone git://github.com/ariya/phantomjs.git
cd phantomjs
git checkout 1.8
./build.sh
For Ubuntu, download the suitable file from http://phantomjs.org/download.html. CD to the downloaded folder. Then:
sudo tar xvf phantomjs-1.9.0-linux-x86_64.tar.bz2
sudo mv phantomjs-1.9.0-linux-x86_64 /usr/local/share/phantomjs
sudo ln -s /usr/local/share/phantomjs/bin/phantomjs /usr/bin/phantomjs
Make sure to replace the file name in these commands with the file you have downloaded.
Be aware this is definitely one way to do it:
$ sudo apt-get install phantomjs
$ phantomjs -v
1.6.0
Sadly, it installs 1.6 and not the latest one, but this works for my purposes.
I know this is too old, but, just i case someone gets to this question from Google now, you can install it by typing apt-get install phantomjs
On Ubuntu for Windows, I found neither apt-get nor npm versions worked for me. What worked was the script from this comment.
For ease of use, I pasted the whole thing into a script file called install_phantomjs.sh, made it executable (chmod u+x install_phantomjs.sh), and then ran it (./install_phantomjs.sh)
Or the latest - 32bit version Linux
sudo wget http://phantomjs.googlecode.com/files/phantomjs-1.9.2-linux-i686.tar.bz2
sudo ln -s /usr/local/share/phantomjs-1.9.2-linux-i686/bin/phantomjs /usr/local/share/phantomjs
sudo ln -s /usr/local/share/phantomjs-1.9.2-linux-i686/bin/phantomjs /usr/local/bin/phantomjs
sudo ln -s /usr/local/share/phantomjs-1.9.2-linux-i686/bin/phantomjs /usr/bin/phantomjs
Installation and Calling Phantomjs
Follow the steps doesn't work, but cloned from others built. (ver2.0)
Bellow the installation procedure by Julio Napurí https://gist.github.com/julionc
Version: 1.9.8
Platform: x86_64
First, install or update to the latest system software.
sudo apt-get update
sudo apt-get install build-essential chrpath libssl-dev libxft-dev
Install these packages needed by PhantomJS to work correctly.
sudo apt-get install libfreetype6 libfreetype6-dev
sudo apt-get install libfontconfig1 libfontconfig1-dev
Get it from the PhantomJS website.
cd ~
export PHANTOM_JS="phantomjs-1.9.8-linux-x86_64"
wget https://bitbucket.org/ariya/phantomjs/downloads/$PHANTOM_JS.tar.bz2
sudo tar xvjf $PHANTOM_JS.tar.bz2
Once downloaded, move Phantomjs folder to /usr/local/share/ and create a symlink:
sudo mv $PHANTOM_JS /usr/local/share
sudo ln -sf /usr/local/share/$PHANTOM_JS/bin/phantomjs /usr/local/bin
Now, It should have PhantomJS properly on your system.
phantomjs --version
I have found this simpler way - Phantom dependencies + Npm
sudo apt-get update
sudo apt-get install build-essential chrpath libssl-dev libxft-dev
sudo apt-get install libfreetype6 libfreetype6-dev
sudo apt-get install libfontconfig1 libfontconfig1-dev
and npm
[sudo] npm install -g phantomjs
Done.
On linux to run hello.js don't forget to add the path of hello.js:
phantomjs YourPathToPhantomjsFolder/examples/hello.js
If you want to use phantomjs easily, you can use it at phantomjscloud.com
You can get the result just by http request.
This is how I place a specific version of phantomjs in /usr/local/bin on my docker containers.
curl -Ls https://github.com/Medium/phantomjs/releases/download/v1.9.19/phantomjs-1.9.8-linux-x86_64.tar.bz2 \
| tar jxvf - --strip-components=2 -C /usr/local/bin/ ./phantomjs-1.9.8-linux-x86_64/bin/phantomjs
or with out ./ depending on OS.
curl -Ls https://github.com/Medium/phantomjs/releases/download/v1.9.19/phantomjs-1.9.8-linux-x86_64.tar.bz2 \
| tar jxvf - --strip-components=2 -C /usr/local/bin/ phantomjs-1.9.8-linux-x86_64/bin/phantomjs
You can get up and running without sudo or npm. Simply download, extract, and add to path.
This has the added advantage of easy backup if you are in the habit of backing up your entire home folder which I highly recommend. This also works with any version of Linux.
➤ cd ~
➤ wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2
➤ mkdir phantomjs
➤ tar xjf phantomjs-2.1.1-linux-x86_64.tar.bz2 -C phantomjs
➤ echo 'export PATH="$PATH:$HOME/phantomjs/bin"' >> .profile
➤ source .profile
➤ phantomjs -v
2.1.1
The disadvantages are:
You will need to manually upgrade
Other users will not have access to this.
You could use a very simple shell script for installing/upgrading
#!/bin/sh
# install_phantomjs.sh $VERSION
$VERSION = $1
printf "Downloading PhantomJS $VERSION...\n"
wget "https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-$VERSION-linux-x86_64.tar.bz2"
printf "Extracting PhantomJS $VERSION to ~/phantomjs...\n"
mkdir ~/phantomjs
tar xjf phantomjs-$VERSION-linux-x86_64.tar.bz2 -C ~/phantomjs
printf "Done! Make sure $HOME/phantomjs/bin is in your path.\n"
Or in a Dockerfile
# Download and setup PhantomJS
ENV PHANTOMJS_VERSION 2.1.1
RUN curl -fSL "https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-$PHANTOMJS_VERSION-linux-x86_64.tar.bz2" -o /tmp/phantomjs.tar.bz2 && \
mkdir ~/phantomjs && \
tar xjf /tmp/phantomjs.tar.bz2 -C ~/phantomjs && \
rm /tmp/phantomjs.tar.bz2
ENV PATH /home/$USERNAME/phantomjs/bin:$PATH
Here is what I did
on my ubuntu 16.04 machine
sudo apt-get update
sudo wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2
sudo mv path/where/you/downloaded/phantomjs /usr/bin
and finally when I do
phantomjs -v
I get 2.1.1
After going through every answer of this thread. I think this is the best solution for installing and running phantomjs in ubuntu.
