How To Fix “ImportError: No module named gtk” in Ubuntu Software Center

Ubuntu 16

The error “ImportError: No module named gtk” is a common issue faced by Ubuntu users when trying to run certain applications. This error indicates that the Python GTK module, which is required by the application, is not installed on your system. In this article, we will guide you through the steps to resolve this issue.

Understanding the Error

Before we delve into the solution, it’s important to understand what the error message means. Python is a programming language that allows its functionality to be extended through modules. Modules are essentially libraries of pre-written code that developers can use to perform common tasks. The “gtk” module is one of these libraries, and it’s used to create graphical user interfaces.

When you see the error message “ImportError: No module named gtk”, it means that the Python interpreter cannot find the “gtk” module. This usually happens when the module is not installed on your system, or if it’s installed but Python doesn’t know where to find it.

Fixing the Error

Step 1: Install the python-gtk2 package

The first step to resolving this error is to install the python-gtk2 package. This package contains the GTK module that Python is unable to find. You can install it using the following command:

sudo apt-get install python-gtk2

In this command, sudo gives you superuser privileges, apt-get is the package handling utility in Ubuntu, install is the command to install a package, and python-gtk2 is the name of the package.

Step 2: Reinstall axi-related packages

If the error persists after installing python-gtk2, it may be due to a problem with the axi module. The axi module is related to the search functionality in Synaptic, and a problem with this module can cause the search box in Synaptic to disappear. Reinstalling the axi-related packages can often resolve this issue. Use the following command to reinstall these packages:

sudo apt-get install --reinstall apt-xapian-index

In this command, --reinstall is an option that tells apt-get to reinstall the specified package.

Step 3: Manually install python-gtk for the specific Python version

If the error still persists, it might be due to having multiple versions of Python installed on your system. In this case, you’ll need to manually install python-gtk for the specific version of Python that’s causing the error. You can do this using the following commands:

wget http://ftp.gnome.org/pub/GNOME/sources/pygtk/2.24/pygtk-2.24.0.tar.gz
tar -xvzf pygtk-2.24.0.tar.gz
cd pygtk-2.24.0
./configure --prefix=/usr
make
sudo make install

In these commands, wget is a utility to download files from the web, tar -xvzf is used to extract the downloaded file, cd is used to change the directory, ./configure --prefix=/usr is used to configure the installation, make is used to compile the source code, and sudo make install is used to install the compiled code.

Conclusion

The “ImportError: No module named gtk” error can be a frustrating issue to deal with, but with the right steps, it can be resolved easily. Remember to always pay attention to the error messages you receive, as they can provide valuable clues about what’s going wrong and how to fix it.
