How To Repair Linux Mint 21

There are times where, for whatever reason, your Linux Mint 21 might encounter hiccups. Fear not! This guide will walk you through the process of repairing your Linux Mint 21 system. This could be useful for those who are experiencing software issues or bugs. The primary focus will be on repairing the system via the command line interface (CLI), as this is typically the most powerful and direct method. We will discuss running system checks, repairing the package management system, and reinstalling the system without losing data.

1. Update and Upgrade Packages

The first step you need to take is to check if your system and all your packages are updated. Software bugs could be causing issues, and these can be resolved by simply updating the package in question. The simplest way to update your system is by using the following CLI commands:

sudo apt-get update
sudo apt-get upgrade

Just a note, sudo apt-get update updates your package list and sudo apt-get upgrade actually installs the new versions of the packages. It’s important to run these commands regularly to keep your system up-to-date.

2. Check for Broken Packages

Another common problem you might face is broken packages. Sometimes, packages can become broken due to dependencies issues or corrupted downloads, and this can cause your system to misbehave. Here’s how you can fix it:

sudo apt-get check
sudo apt-get -f install

The sudo apt-get check command checks for broken dependencies, while the sudo apt-get -f install command fixes them.

3. Use fsck to Check and Repair Filesystem

Linux Mint comes with a built-in tool called fsck (File System Consistency Check) which is used to check and optionally repair one or more Linux file systems. To use fsck, you typically need to boot into recovery mode or a live session. Here are the steps:

  • Reboot your computer and hold down the Shift key as it’s booting up.
  • Select ‘Advanced options for Linux Mint’ and press Enter.
  • Select ‘fsck’ and press Enter.

Once you’re done, your filesystem should be back in good shape.

4. Reinstalling Linux Mint Without Losing Data

If you’re still having issues after trying the steps above, you might want to consider reinstalling Linux Mint. But don’t worry, you can do this without losing your personal data:

  • Boot from your Linux Mint installation disk.
  • Select ‘Start Linux Mint’ and open the ‘Install Linux Mint’ application.
  • When you get to the Installation type window, choose ‘Something else’.
  • Find your existing Mint partition and click ‘Change…’.
  • Do not tick the format box! Make sure the ‘Use as:’ field is set to ‘Ext4 journaling file system’ or whatever you used previously, and that the ‘Mount point:’ is set to ‘/’. Then click ‘OK’.
  • Proceed with the installation as normal.

By keeping the format box unchecked, the installer will keep all files which don’t conflict with the fresh installation. This means your personal data is preserved.

That’s all for this guide! Hopefully, these steps have helped you repair your Linux Mint system. Remember, the key to avoiding these issues in future is regular updates and package upgrades, so make sure to keep your system up-to-date!
