I am using a ubuntu 14.04 and just recently installed the pocketsphinx package. When I try to run the sample robocup.launch file, I get an error saying gconfaudiosrc is no element. Hence when i try sudo apt-get install gstreamer0.10-gconf, I get the following error:
E: Unable to locate package gstreamer0.10-gconf
E: Couldn't find any package by regex 'gstreamer0.10-gconf'
Any sugesstions on what I could do?
For anyone else stuck with the same issue, I solved it by downloading the deb file from here : https://packages.ubuntu.com/trusty-updates/sound/gstreamer0.10-gconf
And then installing it by :
sudo dpkg -i /path/to/deb/file
followed by
sudo apt-get install -f

I'm working on a project in which I've to compile a MicroPython stack and build a firmware file for my STM32 boards. At present, I'm following through the instruction set given on https://docs.micropython.org/en/latest/develop/gettingstarted.html. Hence, to compile the code, I need an ARM cross-compiler (mentioned on the website). After entering the following command on the terminal "sudo apt-get install arm-none-eabi-gcc arm-none-eabi-binutils arm-none-eabi-newlib", I'm getting some errors (basically, unable to locate packages). I tried googling a lot but didn't come across any relevant links. Does anyone know what I need to do?
My pc configurations are AMD Ryzen 5 processor (IdeaPad 3 15ALC6), and I'm using Ubuntu 22.04.1 LTS OS. The snippet of the error is given below:
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package arm-none-eabi-gcc
E: Unable to locate package arm-none-eabi-binutils
E: Unable to locate package arm-none-eabi-newlib
I found the solution based on the discussion available at https://unix.stackexchange.com/questions/377345/installing-arm-none-eabi-gcc and the documentation available on https://mynewt.apache.org/latest/get_started/native_install/cross_tools.html#installing-the-arm-cross-toolchain.
The name and structure of the software changed over time. The arm-none-eabi-gcc is gcc-arm-none-eabi now, and so on.
$ sudo apt-get remove binutils-arm-none-eabi gcc-arm-none-eabi
$ sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install gcc-arm-none-eabi
$ sudo apt-get install gdb-arm-none-eabi
And finally, to verify the downloads, you can run the following commands:
arm-none-eabi-gcc --version
arm-none-eabi-g++ --version
arm-none-eabi-size --version
In /etc/apt/sources.list, make sure the lines with universe are uncommented.
Re-run apt update and (as long as you have a working internter connection) it should work.
I can't OCR files on Alfresco using pypdfocr.
Hello everyone, I'm starting with Alfresco and I'm having some difficulty configuring pypdfocr in Alfresco and using it.
I installed Alfresco on an Ubunto 18.04.5 LTS, using this:
wget https://download.alfresco.com/release/community/201707-build-00028/alfresco-community-installer-201707-linux-x64.bin
I have already done all the necessary configuration, added the files repo.jar and share.jar in the respective folders:
/opt/alfresco-community/modules/platform/simple-ocr-repo-2.3.1.jar
/opt/alfresco-community/modules/share/simple-ocr-share-2.3.1.jar
I added the properties in alfresco-global.properties:
# PYPDFOCR
ocr.command = /opt/alfresco-community/scripts/ocr.sh
ocr.output.verbose = true
ocr.output.file.prefix.command =
ocr.extra.commands = -v -l por
ocr.server.os = linux
I created the script called in the code above:
#!/usr/bin/env bash
# set -o xtrace # Uncomment for debugging / troubleshooting
array = ("$ #")
unset "array [$ {# array [#]} - 1]"
/usr/local/bin/pypdfocr "$ {array [#]}"
I installed the dependencies like this:
apt install gcc libjpeg-dev minizip zlib1g-dev python-dev
However, when I try to perform OCR inside Alfresco, I am getting the following message in /tomcat/logs/:
catalina.out
any help will be appreciated
**** I've tried to solve by installing more dependencies, however it didn't work:
apt-get install wget gcc gcc-c ++ make autoconf automake libtool libjpeg-devel libpng-devel libtiff-devel zlib-devel ocaml ImageMagick ImageMagick-devel
I get the following message:
E: Unable to locate package gcc-c +
E: Couldn't find any package by regex 'gcc-c +'
E: Unable to locate package libjpeg-devel
E: Unable to locate package libpng-devel
E: Unable to locate package libtiff-devel
E: Unable to locate package zlib-devel
E: Unable to locate package ImageMagick
E: Unable to locate package ImageMagick-devel
It would appear that ImageMagick and/or poppler-utils needs installed.
To install ImageMagick: https://www.tutorialspoint.com/how-to-install-imagemagick-on-ubuntu
To install poppler-utils: sudo apt-get install -y poppler-utils
NOTE: you'll need quite a few more dependencies to get this ocr module to work. Specifically, the following:
Tesseract and Leptonica: https://medium.com/#jjagadish.in/install-tesseract-3-04-on-centos-7-4573465d8867
As well as the following packages:
epel-release
python-pip
gcc
libjpeg
minizip
zlib
python
ghostscript
Once you install pip, you'll need to install pypdfocr and pyyaml:
pip install pypdfocr
pip install pyyaml
I would suggest getting it to work at the command line first using an example pdf:
/opt/alfresco-community/scripts/ocr.sh -v -l por test.pdf test.pdf
I am a newbie on Linux kernel. I was trying to install Linux header on ubuntu. I first tried
sudo apt-get install linux-headers-$(uname -r)
However, since the output of $(uname -r) is 4.4.0-18362-Microsoft, the installation gives me the error:
E: Unable to locate package linux-headers-4.4.0-18362-Microsoft
E: Couldn't find any package by glob 'linux-headers-4.4.0-18362-Microsoft'
E: Couldn't find any package by regex 'linux-headers-4.4.0-18362-Microsoft'
By searching on the internet, I found that linux headers do not exist on WSL. Therefore I tried something that is recommended on the internet, by doing
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get install linux-generic
sudo apt-get install linux-headers-generic
Then I got a successful installation under /usr/src/linux-headers-4.15.0-51-generic and /usr/src/linux-headers-4.15.0-51. However, my team uses a makefile where the directory of the Linux headers is referred to using $(uname -r), which is still 4.4.0-18362-Microsoft. So whenever I do make, it still gives me the error
can't read /usr/src/linux-headers-4.4.0-18362-Microsoft/...
Is there anyway I can install the headers or change $(uname -r) such that I can use $(uname -r) to refer to the directory?
Create a symlink from /usr/src/linux-headers-4.15.0-51-generic to /usr/src/linux-headers-4.4.0-18362-Microsoft/
sudo ln -s /usr/src/linux-headers-4.15.0-51-generic /usr/src/linux-headers-4.4.0-18362-Microsoft
I'm using Ubuntu 18.04.2 LTS and had a similar issue - but it wasn't Microsoft:
E: Unable to locate package linux-headers-4.15.0-51-generic-generic
E: Couldn't find any package by glob 'linux-headers-4.15.0-51-generic-generic'
E: Couldn't find any package by regex 'linux-headers-4.15.0-51-generic-generic'
For me worked fine after I did as below:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install linux-generic
sudo apt-get install linux-headers-$(uname -r)
My self naitik joshi. I stuck with one major problem on ubuntu 14.04
When i run apt-get command in terminal it says:
Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_trusty_main_i18n_Translation-en%5fIN
E: The package lists or status file could not be parsed or opened.
Any help appreciated.
Thanks in advance for your time and consideration.
-Naitik
sudo rm /var/lib/apt/lists/* -vf
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
Open your terminal run the command wget https://dl.dropbox.com/u/8850924/fixpackage
chmod +x ./fixpackage
sudo ./fixpackage
This would generally install the fresh broken package for you and its working .
Sublime-text is a fast editor for Windows and Linux. I failed to install sublime text 3 on AWS Ubuntu 14.04.1 LTS using the following commands:
sudo add-apt-repository ppa:webupd8team/sublime-text-3
sudo apt-get update
sudo apt-get install sublime-text-installer
Results in following error message:
p: cannot create regular file "/usr/share/icons/hicolor/16x16/apps/":
No such file or directory dpkg: error processing package sublime-text-installer (--configure):
subprocess installed post-installation script returned error exit status 1
I see following directories under /usr/share/icons/hicolor/
32
48
64
So, I created 16x16 subdirectory, but then it gives an error for 32x32 directory doesnot exist. Did anyone experience this problem before? I will appreciate any help.
sublime-text is a GUI application that needs a GTK installation. Your server is missing that dependency. (In a perfect world, it should be a dependency of the package of course.)
Install libgtk2 (as root):
apt-get install libgtk2.0-common
and then reinstall sublime-text, probably using:
apt-get purge sublime-text-installer ; apt-get install sublime-text-installer
