I think I know what the problem is. The version was bumped to v33.1 in the code but not in the debian changelog. I'll fix that and start a new build which should then rebuild the packages with the correct version.
Don't know if this is related or not but this morning I installed the mythbuntu 33 ppa in preparation for upgrading from my 32 installation. When I try to update I'm getting this error from the 33 ppa: The repository 'http://ppa.;aunchpad.net/mythbuntu/33/ubuntu bionic Release' does not have a Release file.
