Comment 8 for bug 1897784

It's hard to pin down what other new packages could have made it onto the users system because of the way Ubuntu rolls out releases in a "phased" manner:

This is happening simultaneously for all sorts of packages too, at various stages in the phasing process. So unfortunately, there's no way to really get a sense of other new packages that might be causing the issue.
