2. Clear APT Cache
Ubuntu keeps a cache of the installed packages which are downloaded or installed earlier even after uninstallation. Cache files in this location /var/cache/apt

To check the disk space consumed you can use the following command.

sudo du -csh /var/cache/apt
Enter fullscreen mode Exit fullscreen mode

Output will be look like

Now you can clean this cache using the following command.It will clean up entire cache which frees up more space.

sudo apt-get clean
Enter fullscreen mode Exit fullscreen mode

If you wish to clean up only the outdated packages, you can use the following command.

sudo apt-get autoclean
Enter fullscreen mode Exit fullscreen mode

3. Remove unused packages and Kernels

You can remove the kernels & packages that are no longer needed and that are installed from Ubuntu archive while system updates using the following command.
Note: This command will not remove the kernels that are installed manually.

sudo apt-get autoremove --purge
Enter fullscreen mode Exit fullscreen mode
