Any operating system gets congested overtime as applications and programs are installed and removed. This system overload can have a negative impact on system performance. Cleaning up your system to free up disk space is a necessary task. There are many tools that help us easily clean up system junk files.

Here at LinuxAPT, we shall look into a few graphical tools that can be used to clean up Ubuntu and Linux Mint systems.


How to Remove unnecessary packages from Ubuntu and Linux Mint System ?

Whenever some applications or even system updates are installed, these are downloaded by the package manager and then stored in the cache before installing them, in case they need to be installed again.

If the installation was successful, Ubuntu does not delete these packages and they remain cached.

So cleaning these packages is recommended to save disk space, improve your PC performance, and speed up boot times.

These packages are stored in the / var / cache / apt / archives folder.

To remove all this garbage from the system, just run the following command from the terminal:

$ sudo apt-get -s clean

This command will clean up the following system directories:

  • / var / cache / apt / archives / partial / *
  • / var / lib / apt / lists / partial / *
  • /var/cache/apt/pkgcache.bin
  • /var/cache/apt/srcpkgcache.bin


Best tools to Free Up Space on Ubuntu and Linux Mint include:

1. Stacer

Stacer is a GUI application built to optimize Linux systems. It provides a system cleanser that can be used to monitor and free up system resources. The System cleaner section allows you to search for and remove potentially unwanted files of four different types:

Apt Cache: downloaded package files are cached every time you use the apt command to install packages. This is useful for reinstalling those packages in the same version without having to download them again. However, to free up storage space, you may choose to erase them.

Crash Reports: These are generated whenever an application crashes, and sent to the application’s developer for troubleshooting purposes. Stacer can remove such files.

System Logs: These are log files from system processes that can be deleted to free up space.

App Cache: Cache files are stored by applications to increase performance. From here, you may delete cache files for a variety of apps.

To install Stacer on Ubuntu, run the below command:

$ sudo apt install stacer

How to Remove old kernels from the Ubuntu / Linux Mint system  ?

1. As we should know, the Linux Kernel is the heart of the system, but it is also known that it is updated every so often, so they are released new versions which are installed in the system displacing the old versions which remain stored without being eliminated.

For this we must type the following command:

$ sudo dpkg 'linux-image *' --list

2. Next, they must identify their oldest kernels and execute the following command to remove the previous versions.

Just replace xxxxx with the version of Linux you want to delete:

$ sudo apt-get remove linux-image-xxxxx

3. As an alternative, an easier way to clean up these old kernels is to use 'autoremove':

$ sudo apt-get autoremove  --purge
