How To Remove Old Ubuntu Core Snaps

Ubuntu 18

Ubuntu Core Snaps are a convenient way to distribute and manage applications in a Linux environment. However, over time, you may accumulate old versions of snaps that are no longer needed, taking up valuable disk space. In this article, we will guide you through the process of identifying, unmounting, and removing these old snaps from your Ubuntu system.

Quick Answer

To remove old Ubuntu Core Snaps, you need to identify them using the mount command, unmount them using the umount command, and then delete them using the rmdir and rm commands. However, it’s important to proceed with caution as removing snaps manually can have unintended consequences.

Understanding Ubuntu Core Snaps

Before we begin, it’s important to understand what Ubuntu Core Snaps are. Snaps are containerized software packages that are simple to create and install. They auto-update and are safe to run. If you’re interested in more about snaps, you can read about them on the official Ubuntu website.

Identifying Old Snaps

The first step in removing old snaps is identifying them. To do this, we use the mount command, which will display all mounted filesystems. By filtering the output with grep, we can narrow down the list to only show snaps.

mount | grep snap

This command will display a list of all mounted snaps, including their version numbers, snap names, and mount points.

Unmounting Old Snaps

Once you have identified the old snap versions you wish to remove, the next step is to unmount them. The umount command is used for this, followed by the mount point of the snap.

sudo umount /snap/ubuntu-core/352

In this example, ubuntu-core/352 is the mount point of the snap we want to unmount. The sudo command is used to run the command with root privileges, which is necessary for unmounting filesystems.

Deleting Old Snaps

After unmounting the old snaps, you can delete them if they are no longer needed. This is done with the rmdir command, which removes empty directories, and the rm command, which removes files.

sudo rmdir /snap/ubuntu-core/352
sudo rm /var/lib/snapd/snaps/ubuntu-core_352.snap

In these examples, /snap/ubuntu-core/352 is the mount point directory we are removing, and /var/lib/snapd/snaps/ubuntu-core_352.snap is the snap file we are deleting.

Caution

While this process can help free up disk space, it should be done with caution. Removing snaps manually can have unintended consequences if not done correctly. It’s also recommended to keep the latest version of each snap installed to ensure system stability and security.

Conclusion

By following these steps, you should be able to identify, unmount, and remove old Ubuntu Core Snaps from your system. Remember to proceed with caution and always keep your system’s stability and security in mind. If you have any questions or run into any issues, the Ubuntu community is a great resource for help and information.
