2. Delete unnecessary files (based on your needs ). There are several common files that can be deleted.

(1) Clear the downloaded cache package

When we install software through sudo apt-Get install in Ubuntu, all downloaded packages are cached in the/var/Cache/APT/archives/directory. To clear these downloaded cache packages, run the following command:
Sudo apt-Get autoclean
Sudo apt-Get clean

(2) Clear unnecessary packages

We know that when installing software in Ubuntu, the dependencies of the software are usually automatically installed. After we delete the software, we may need to manually delete its dependencies. You can run the sudo apt-Get autoremove command to solve this problem.

3. Restart. OK.
