Public bug reported:

Here's the report from the failed upgrade. I'll attach the requested
files:

Processing triggers for man-db ...
dpkg: error: dpkg status database is locked by another process
Error in function:


A fatal error occurred

Please report this as a bug and include the files
/var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in
your report. The upgrade has aborted.
Your original sources.list was saved in
/etc/apt/sources.list.distUpgrade.

SystemError: E:Sub-process /usr/bin/dpkg returned an error code (2)


Could not install the upgrades

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