How To Enable Snap And Install Snap Packages On Linux Mint 20?


With Linux Mint 20, the Mint dev team has decided to disable the snap support and block installation of Ubuntu snap packages by default. Though Linux Mint has never supported the snap, it has allowed installing Ubuntu snap store or snapd open-source client in previous releases by default.

Now, if you want to enable snap support to install snap apps in Linux Mint 20, the usual command sudo apt install snapd to install snapd will not work. This is because APT Package Manager blocks the installation stating “Package snapd is not available” and “Package snapd has no installation candidate.”

If you want to know the reason for dumping snap support, read the Mint blog post here. Clem Lefebvre, head of the Linux Mint project, has mentioned that the chromium snap package acts as a backdoor and installs the Ubuntu store without user consent. Hence, in Linux Mint 20, APT will forbid snapd from getting installed.

But there is also a way round to surpass the restriction from APT and install snap apps using snapd tool. All thanks to Leo Chavez, a co-host on the MintCast podcast, who shared the method on his Twitter post.

Hence, in this article, I will guide you on how to enable snap support in Linux Mint 20 and install snap packages with or without deleting nosnap.pref file:

Linux Mint Blocks Ubuntu Snaps

As you can see in the picture below, if you run the usual command sudo apt install snapd, it throws an error saying the snapd package is missing or has been obsolete.

Linux Mint 20 disabled snaps

Even if you search for snapd in the Software Manager of Linux Mint 20, instead of an Install button, you’ll get an unending spinning wheel.

So, the first thing we need to do to install snap packages is to enable the default disabled or blocked snap support on Linux Mint 20.

To give you a quick overview, here is a list of things I’ll go step-by-step to guide you from enabling snap support to installing snap packages and also disabling snap support back:

  • Enabling snap support on Linux Mint 20
  • Installing snapd tool
  • Install snap packages without removing nosnap.pref file
  • Disabling snap support on Linux Mint 20

How To Enable Snap Support On Linux Mint 20?

To enable snap on Linux Mint, you don’t have to go through a list of commands. You only need to know about a single file and tweak it to allow installing snapd.

The Mint dev team has included a new file named nosnap.pref in the directory /etc/apt/preferences.d.This file contains only three lines of code that blocks snapd package installation.

Package: snapd
Pin: release a=*
Pin-Priority: -10
Linux Mint 20 — nosnap.pref file

Hence, you only need to either comment these three lines of code or delete the whole file nosnap.pref to fully allow installing snap packages. I would recommend that you should remove the file only if you don’t wish to disable the snap again.

sudo rm /etc/apt/preferences.d/nosnap.pref
Linux Mint 20 — remove nosnap.pref file

Once you delete or hide the block of code, Linux Mint 20 is ready to install snapd and then snap packages.

How To Install Snapd On Linux Mint 20?

We can now install snapd tool that won’t be blocked by APT package manager. To install it, run the command:

sudo apt install snapd
Linux Mint 20 — installing snapd

Once the installation finishes, you now have the full snap tool to install and manage snap packages. If you want to know the version and all commands available, run:

snap version
snap --help
Linux Mint 20 — Snapd enabled and installed

Install Snap Packages On Linux Mint 20

Here we reach the important section that you must be waiting for. As we now have full support and tools for the snap, we can install any snap application by running the command:

sudo snap install <app-name>
Linux Mint 20 — Install Chromium using snap

Install Snap Packages Without Deleting nosnap.pref File

This is another method to install snap packages if you don’t want to interfere with nosnap.pref file. But this method might be tedious for some people as it involves knowing the version number of snapd you want to use.
To install the snap package, you first need to have snapd version. Then run the command:
sudo apt install <app-name> snapd=VERSION
Linux Mint 20 — Installing snap packages using version

How To Disable Snap Support On Linux Mint 20?

If you’ve removed the nosnap.pref file to enable snap, create a new file with the same in the directory /etc/apt/preferences.d/ and add the above mentioned three lines of code.

Linux Mint 20 — disable snap

Adding the file will again disable the snap support and now you can’t install snap packages.

Wrapping Up

I hope you learned how to install snap packages on Linux Mint 20 by enabling the locked snap support first. Besides snapd, you can also use snap’s alternative Flatpak. Linux Mint has default support for Flatpak.
