Comment 13 for bug 1912060

@Joshua Peisach: On ubuntu version released the only way to update is SRU: https://wiki.ubuntu.com/StableReleaseUpdates
Do a backport (for example for focal in focal-backports) will require that user enable backports (if not) and install it; user that don't know and do it will not have the fix.
The patch have same changes to code and only changelog changes, version of the caribou patched is also the same and there should be without risk, anyway I tested build in focal installed and checked that issue is not reproducible anymore (and no regression is showed); a fast test in groovy it would still be better although it is very unlikely that there are differences on result.
