I’ve got lsb-release installed on arch now, nothing changed.
I’ve also reinstalled grub using THIS tutorial, nothing changed either.
What confuses me is (as I posted above), while updating grub it tells me that it has found Arch on nvme0n1p2, but it then goes on adding an entry for UEFI Firmware Settings and detecting snapshots…why does it ignore the Archdistro it found?
