While the version of ubuntu-drivers-common in the release pocket for Ubuntu 20.04 LTS has code for "system_device_specific_metapackages" it seems that some users[1] have strange versions of ubuntu-drivers-common installed and are receiving Tracebacks with an attribute error. So it seems like the update-notifier SRU would have benefited from a versioned dependency on ubuntu-drivers-common.
