It’s worth noting that all of these “app stores” are just front ends for your native package manager (apt or pacman for example) and flatpak, so it’s worth learning the difference between the two (native and flatpak) but it doesn’t really matter if you install packages using GUI (the “app store”) or CLI (package manager or flatpak install command) l. It comes down to preference and I doesn’t agree with @[email protected] that it should be a last resort to use CLI, but if you are a beginner, yeah, it is probably easier to use the " app store" things.

Thanks for your reply, i’ll try the traceroute thing when i’ll be back home in a few days :)
