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 @Presi300@lemmy.world 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 :)

I have my seeding capped at 1.0 ratio because I have torrent on my home server which I use also for other things like matrix and it works like shit when it's seeding a lot. I already figured out a solution but I need money for that, so for the time being it has to be like this.
