I think there is more than one app named “System Monitor”. I am on 26.04 and they used a new app named “Resources”, so in App Center I see two apps named “System Monitor” that can both be installed. One is a Snap and one is a Deb.
I don’t even know what “App Center” is - and I run Ubuntu 24.04… I always launch stuff through the dash/dock…
I’ve seen similar happen where I had Brave installed as both a DEB install and a SNAP - there were two Brave Icons in the dash/dock… I removed one of them (probably the snap)…
It doesn’t bother me enough to even care… I just don’t want two versions of an app installed… I’d preference the package manager installed version over the SNAP version… However Ubuntu is sneaky enough to snap install something even if you “sudo apt install $PACKAGE” - which bothers me a bit - but not enough to lose sleep…
I don’t “LOVE” snaps (never mind “the bomb”) - but I learned to stop worrying…
It’s probably nearly 10 years since I used Chromium as my default browser on Ubuntu (I stopped for two reasons - 1 - Ubuntu delivered it as a snap 2- Google API blocked Chromium users from using their Google Account for sync).
10 years ago - my laptop daily driver showed a noticeable (it was an Gen4 or 5 i5 I think with 16 GB DDR3) lag in load time for SNAP apps like Chromium. So I avoided them… No such noticeable lag on a more modern laptop or desktop machine… I guess I should care… I don’t like bloat…
Yes by uninstalling snapd, but if you want Firefox it’ll still install as a Snap, as that is the only version in their repositories, unless they have now released Deb version in 26.04? So Ubuntu will reinstall Snapd to install Firefox.
Linux Mint took over Firefox as a Deb file in their repos. Snaps as I have said many times on this site are unreliable, way too heavy on resources, easily get infected with Malware. The latest Malware back in January 2026 Users have reported that Snap packages keep getting infected. Canonical need to up their Security, or they don’t give a monkey’s armpit about it?
