I have a question about package management in Ubuntu. I know that there exist standard repositories from which I install software in form of packages. Suppose I want to install some software that don't exist in standard repositories. What should I do? Of course I want to track and manage this software as easy as software from standard repository. What is the canonical way of managing such software on Linux, especially Ubuntu OS? Any answer would be appreciated.
You can manage packages that are installed outside of the standard APT repositories, but not that easy. Packages that are installed with apt install /path/to/package-downloaded-elsewhere-but-not-from-repo.deb are not usually receive updates, so you'll only stuck with install and uninstall stuff.
I'm somewhat of a linux noob, but I'm trying to use a microcomputer with aarch64 Architecture. I am trying to download software using wget and a Public Cert Key for software developed for x64/AMD64. When I try to run
sudo apt-get install <package>
I get:
E: Unable to locate package <package>
I am assuming it is because it was developed for AMD64. From everything I've found, I think I need a cross compiler to translate the binary from AMD to ARM,but nothing I've found has helped me get any closer to actually installing my desired package. Can anyone give me an ELI5 version or point me in the direction of how to educate myself better on system architectures?
You may have better luck using update command:
sudo apt-get update
to upgrade packages lists
sudo apt-get search <generic name of package>
and then
sudo apt-get install <package name found in search>
The generic name I mean "apache" instead of "apache-php-modlib"
How to install libleveldb-dev (leveldb development libraries) on windows? I need this to be downloaded so I can install plyvel. Thank you in advance I hope someone is familiar with this process.
The way to install this on Linux is :
sudo apt-get install libleveldb-dev
But I need to install this on windows. Is there a similar easy way to do this in the windows command prompt? Related Link: https://plyvel.readthedocs.io/en/latest/installation.html#build-and-install-plyvel
Just answering for the next ones, there is a version of plyver just for windows that doesnt require all this suffering. just try: "pip install plyvel-win32" if you have the visual libraries should work.
I'm installing "FASTX Toolkit" using yum but not able to install .My operating system is RHEL v7 with 64 bit
please give me some suggestion how to solve this
A friend and I are interested in training the tesseract-OCR engine for a CV project. We tried using some wrappers such as PyTesser and pyocr, but the results are currently not as accurate as we need them to be. As such, we want to try training the tesseract to perform better for our purposes (i.e. identifying text on food labels), but are having some trouble installing the training tools.
What we've tried:
Looking on the google code website, the 'Compiling' page on the tesseract's google code wiki says the training tools are only available on version 3.03. However, the google code 'Downloads' page for tesseract-ocr only has the materials for 3.02. The bottom of the 'Compiling' page also has some comments about installing version 3.03 on Windows and OSX, but no comments yet for Linux users.
There also appears to be some sort of 3.03 source package for Ubuntu but we're not sure how to access it on our computers and the 'Compiling' page says we need to run these commands:
make training
sudo make training-install
We've also found a google group thread about tesseract 3.03 but again it seems like these posts do not include advice for Linux users (unless we missed something during the initial read).
Is this actually a really simple command-line install problem? Or, is there a way train tesseract with 3.02 (which we currently have installed)? Have we been looking at the wrong places for information?
Any advice or links to instructions for installing tesseract-ocr 3.03 for Linux distributions would be greatly appreciated! Thanks.
Tesseract can directly be installed in Ubuntu 14.04 using
sudo apt-get install tesseract-ocr
I don't have any idea if you can do it in older version of Ubuntu because the repo might be updated in later version of Ubuntu.
I had an aws ubuntu 14.04 instance.
when I tried installing Tesseract with
sudo apt-get install tesseract-ocr
It retuned package not found
But this worked for me.
sudo apt-get update
sudo apt-get install tesseract-ocr
Ubuntu is a debian based Linux distribution. The tesseract package you find will most likely be a debian package which will contain tesseract and the required default language files to allow you to run/train tesseract. You do NOT want the source package -- unless you just want to compile it yourself -- no need. You will not have to build tesseract, you just need to install the package. First, it appears you are new to Ubuntu, so please ready InstallingSoftware. It can be as easy as opening up an x-term and issuing the command apt-get install tesseract-pkgname (note: that means whatever the package name is).
There is no shortcut, take the time to understand whether you have a .deb package on your box that need to be installed or whether you are installing from a remote repository. The link above explains how to handle both.
Here is a specific Ubuntu thread dealing with installing tesseract Tesseract 3.0 + Ubuntu 10.04 Installation Guide Hope that helps. Tesseract is very good software.
I don't have any instructions for building Tesseract 3.03 for Linux specifically (I'm on Mac), but here's a link to download the source code for the 3.03 release candidate: https://tesseract-ocr.googlecode.com/archive/3.03-rc1.tar.gz
First run below command
sudo apt-get install tesseract-ocr
It will install tesseract version 3.04
Run below to update the tesseract
sudo apt-get --only-upgrade install tesseract-ocr
It will update tesseract to 4.1.3
