Quick Answer

To fix the "error while loading libgtkglext-x11-1.0 libraries" in Ubuntu command line, you can add the Universe repository, update the package list, and install the required library using the libgtkglext1 package.

Understanding the Error

The error message “libgtkglext-x11-1.0.so.0: cannot open shared object file: No such file or directory” is basically indicating that the system is unable to find the required library file to execute a specific application. In our case, the missing library is libgtkglext-x11-1.0.so.0.

Prerequisites

Before we proceed with the resolution, make sure you have:

  • An Ubuntu system with terminal access
  • Sudo or root access to run administrative commands

Step 1: Adding the Universe Repository

The first step is to add the Universe repository to your system. The Universe repository contains community maintained free and open-source software.

To add the Universe repository, open a terminal window and run the following command:

sudo apt-add-repository universe

The sudo command is used to run the following command as a root user. apt-add-repository is a script which adds an external APT repository to either /etc/apt/sources.list or a file in /etc/apt/sources.list.d/. Here, ‘universe’ is the repository we are adding.

Step 2: Updating the Package List

Once you have added the Universe repository, the next step is to update the package list to include the newly added repository.

To update the package list, run the following command:

sudo apt-get update

The apt-get update command is used to download the package lists from the repositories and “update” them to get information on the newest versions of packages and their dependencies.

Step 3: Installing the Required Library

Now that we have updated our package list, we can proceed to install the libgtkglext1 package which contains the required library.

To install the libgtkglext1 package, run the following command:

sudo apt-get install libgtkglext1

The apt-get install command is used to install the specified package. Here, ‘libgtkglext1’ is the package we are installing.

After successfully installing the library, you should be able to run the application without encountering the shared library error.

Troubleshooting

If you still face issues after following the above steps, ensure that you have the correct version of the library for your system. You can check the available versions and download the appropriate deb-package from the Ubuntu Packages website.

Remember to replace “focal” in the URL with your Ubuntu version if you are using a different release.
