[Bug 1743169] [NEW] server upgrade to aardvark - dpkg: error: dpkg status database is locked by another process

[Niels Egberts]

Public bug reported:

I ran do-release-upgrade on my server with zesty. But some upgrades were
not performed, it asked me to file a bug:

The upgrade has aborted. Your system could be in an unusable state. A
recovery will run now (dpkg --configure -a).
