UpgradeStatus: No upgrade log present (probably fresh install)
It installs and uninstalls cleanly for me, but I've seen that was on a purge anyway.
In the logs I couldn't find an obvious issue triggering this, but since you were removing it it might be a known thing e.g. dur to former config or other changes.
That said, setting to incomplete - please provide further detail on the actual issue and how to reproduce it if this is more than just an auto-report on the crash.
