A considerable number of users have started to use Linux to test and work on the server. Once you make up your mind to install Linux, you may find that it is not terrible, in many cases, the usage is much easier and faster than you expected.

I think many of my friends started from Ubuntu, and most new users will try a lot of applications. This causes Ubuntu to consume a lot of disk space overhead, especially after installing and uninstalling a large number of applications. However, it is confusing for new users to release unnecessary Ubuntu disk space.

When we install software packages in Ubuntu, sometimes the system automatically installs necessary software packages to solve the dependency problems that are widely known in Linux. However, when you Uninstall a software package, the software package installed due to dependency does not always be deleted, and it will occupy unnecessary disk space when it is left in the system. If such software packages accumulate less, they will occupy a large amount of unnecessary Ubuntu disk space.

Sudo apt-get autoremove
