I checked further and I think the problem might actually be in this patch: https://salsa.debian.org/printing-team/hplip.v2/-/commit/18478a1d60f3d304cc36ceed4a471a222ae59011 The method get_distro_std_name() is removed in this patch but in the update to 3.22.10 the method is used. You should check that patch again before applying it. Claudio
