After creating a fresh installation of Ubuntu 24.04, I installed DEB Firefox from APT by following Mozilla’s instructions from here. But I noticed that it was secretly replaced with Snap Firefox. I was able to verify this by checking the About Firefox page. This is the third time I noticed this.
Linux just isnt transparent about some things. Beginners most have problems when they use a GUI tool and then have to still edit a file. Like dirt example, adding a new drive using GUI disk utility and then sometime in the future disconnecting the drive and being forced into emergency mode.
I’d suggest the KDE flavor of Debian, then. Its settings manager is divine, and its software management platform ties every other package management system in (apt/dpkg for Debian, yum for Redhat, pacman for Arch, plus flatpak, nixpkg, and even snaps if you absolutely must). By default starting in Plasma 6.0.
More to @fmstrat’s point, and to suggest a possible cause your friend had that impression: if you install the Minimal flavor of any distro, you’re going to get a minimal experience.
