I am using Ubuntu 19.04. When I need to install some new package I usually do it by running
sudo apt install from the command line. To keep things updated I use "Software Updater" (update-manager), sometimes it pops up to remind me and sometimes I run it myself to make sure everything is up to date.
However, recently I have installed some packages using
snap install instead of apt, and now I am not sure if I should run something more than "Software Manager" to make sure everything is updated.
Does "Software Updater" only update software installed using apt, or also software installed using snap?
Do I need to run something else in addition to "Software Updater", and if so, what?
Also: is it a bad idea to mix the "apt" and "snap" ways of installing things?
