How to Install Snap on Linux Mint 21.3 | Installing Snap on Linux Mint 21.3 | Snap is available for the latest release of Linux Mint, 21.3 (Virginia), and for older releases from Linux Mint 18.2 (Sonya) onwards.
From Linux Mint 20 onwards, a file called nosnap.pref needs to be either moved or removed from /etc/apt/preferences.d/ before Snap can be installed. This can be accomplished from the command line, and the following command (for example) moves nosnap.pref to a renamed nosnap.backup file in your Documents directory:
sudo mv /etc/apt/preferences.d/nosnap.pref ~/Documents/nosnap.backup
With the file removed from its original location, the package database needs to be updated next:
sudo apt update
To now install snap from the Software Manager application, search for snapd and click Install.
Alternatively, snapd can be installed from the command line:
sudo apt install snapd
To complete the installation, either restart your machine, or log out and in again.
To test your system, install the hello-world snap and make sure it runs correctly:
$ snap install hello-world
hello-world 6.4 from Canonical✓ installed
$ hello-world
Hello World!
