Installing Snap Packages on Linux Mint 21 is not as straightforward. If the snap package is installed without doing the steps below, it throws an error as below:
package snapd has no installation candidate.
However, snap can still be enabled, and snap packages installed on it.
To install snap, open a terminal window and enter the following commands:
$ cd /etc/apt/preferences.d <enter>
$ sudo mv nosnap.pref nosnap.pref.bk <enter>
To install snap, enter the following command:$ sudo apt-get install snapd <enter>
Sometimes, there are packages that are only available as snap packages and there is no other choice but to enable snap on Linux Mint 21 to install them.
