If I install software from .deb file, do I still get the updates & upgrades when I run sudo apt update / upgrade ? Or is flatpak the way to go? I’m not very familiar with flatpak, so I’m trying to avoid, but it seems that cons are limited. I’m currently running mint cinnamon (how original, I know), and asking because i can’t seem to add mullvad-vpn stable repo. Thank you for your help,
For mullvad vpn the client will tell you when there’s an update available by a very obvious flag in the app that you click on to download it then click/double click on the file out of the downloads to get debi to install it.
To answer the broader question, where ever possible install apps via software manager, that way they are updated with apt / update manager.
I would suggest using flatpacks sparingly as they are disk hogs.
Thank you very much for this clear answer.
