How can you completely remove a package in Ubuntu Linux?

To completely remove a package in Ubuntu Linux, you can use the apt-get command with the purge option.

For example, to remove the package mypackage, you can use the following command:

sudo apt-get purge mypackage

This will remove the package, along with its configuration files.

Alternatively, you can use the apt command with the --purge option:

sudo apt remove --purge mypackage

Both of these commands will remove the package and its dependencies, but will leave any unneeded dependencies installed on your system. If you want to remove these as well, you can use the autoremove option:

sudo apt-get purge mypackage && sudo apt-get autoremove

or

sudo apt remove --purge mypackage && sudo apt autoremove

This will remove the package and its dependencies, as well as any unneeded dependencies that were installed as a result of installing the package.

Here are a few more things to consider when removing a package in Ubuntu:

  • If you want to remove the package and its dependencies, but keep the configuration files, you can use the remove option instead of purge. For example:
sudo apt-get remove mypackage

or

sudo apt remove mypackage

This will remove the package, but will leave the configuration files in place.

  • If you want to remove a package and all of its dependencies, but keep the configuration files for both the package and its dependencies, you can use the autoremove option without the purge option. For example:
sudo apt-get autoremove mypackage

or

sudo apt autoremove mypackage

This will remove the package and its dependencies, but will leave the configuration files for both the package and its dependencies in place.

  • If you want to remove a package and all of its dependencies, including the configuration files for both the package and its dependencies, you can use the autoremove option with the purge option. For example:
sudo apt-get purge mypackage && sudo apt-get autoremove --purge

or

sudo apt remove --purge mypackage && sudo apt autoremove --purge

This will remove the package and its dependencies, as well as the configuration files for both the package and its dependencies.

I hope this helps! Let me know if you have any further questions.
