Comment 23 for bug 1828534

Also we could consider cherry-picking the fixes back to rocky and stein packages. They've just not landed upstream. It would fix py2->py3 upgrades, which this bug reported. But I believe the fix would break py3->py3 upgrades. The charm deploys py3 as of rocky. The package was py2 by default in rocky (with py3 available) and py3 by default in stein.
