People doing the 30 days linux Challenge are having several problems because of Mint's old packages and technology. Why people still recommend it when there is Fedora and Opensuse with KDE and Gnome?
Older packages, but not too old, generally provide better stability. Problems can also come from packages being too new and not having all the standout issues worked out of them.
around 1 year and a half, thats way too long, considering the Pipewire, OBS, Kernel, Gaming and other drivers updates. Not even mentioning all the updates KDE and Gnome just got in the last 3 months.
Newer kernels are available, they even have a gui for it. Why would a Cinnamon user care about KDE or GNOME updates? (Some of which are broken on Fedora, like rdp login)
