I don’t think anyone is doing something with these. A abrt-applet still usefull? what can I do with it? How does it help me?
FWIW, there was some discussion about it here:
https://forge.fedoraproject.org/workstation/tickets/issues/503
That is very interesting. So why is it still installed with F44? I installed this box about 1.5 month ago but I still see the gui.
Should I sudo dnf remove abrt-desktop or sudo dnf remove abrt-gui?
Personally, I would use sudo dnf remove 'abrt*'.
If I do that, will coredumps be cleaned up automatically, or is this something manual?
It won’t remove coredumps. You’ll want to run sudo rm -rf /var/spool/abrt after you remove those packages.
Why on earth would I want that?
You asked how to remove the coredumps after uninstalling Abrt. That command is how you would accomplish that goal.
