Description of problem: Previously I used Bugzilla._update_bugs() from python-bugzilla to update the short description (summary) and comments of bugs. This does not work anymore. Also I cannot find a way to do this using any other method documented in https://bugzilla.redhat.com/docs/en/html/api/extensions/RedHat/lib/WebService/CompatBugzilla.html
Use Bug.update instead. https://bugzilla.redhat.com/docs/en/html/api/Bugzilla/WebService/Bug.html#update
