As you install and remove software in Ubuntu, the APT package manager accumulates a cache of downloaded packages. Over time, this cache can consume significant disk space. In this guide, we’ll show you how to clean up the package cache efficiently and reclaim valuable storage.

Step 1: Clean the APT Cache

The APT package manager maintains a cache to speed up installations, which can be cleared to free up space.

Remove All Cached Packages

To clear the entire APT cache, use the following command:

sudo apt-get clean

This command removes all files from the /var/cache/apt/archives directory, significantly reducing disk usage.

Remove Old Cached Packages

If you prefer to remove only outdated packages that can no longer be downloaded, run:

sudo apt-get autoclean

This command deletes cached packages that are no longer available in the repositories, keeping only those that can still be installed.

Step 2: Check Cache Size

Before you clean the cache, it’s helpful to know how much space it is using. To check the size of the APT cache, run:

du -sh /var/cache/apt/archives

This command will display the total size of the cache, allowing you to see how much space you can reclaim.

Step 3: Remove Unused Packages

To further free up space, consider removing packages that were automatically installed but are no longer required. Use this command:

sudo apt-get autoremove

This command helps keep your system tidy by removing unneeded dependencies and packages.

Conclusion

By following these steps, you can efficiently clean up your package cache in Ubuntu, freeing up disk space without negatively affecting your system’s performance. Regular maintenance of your APT cache is a good practice, especially for users who frequently install and remove packages.
