I know that I can update a snap package using
sudo snap refresh <package>
But is there a way to update all snaps, like
sudo apt dist-upgrade
sudo snap refresh
Will do this. It is part of snapd 2.0.8, which landed 2016-06-13 in xenial-updates.
snap refresh --list
Only lists the updates without refreshing the packages.
snap info <snap name>
Can show which versions are available for a particular package.
You can also update a specific application if the other method fails
sudo snap refresh <Application>
Example usage:
sudo snap refresh slack --classic
