Happens to me to.

First seen when trying to install 5.2.22.
I abandoned that, cleared things up and re-installed 5.2.20 - which worked OK.

I've just tried installing 6.0.3-BETA3. That suffered this issue too.
I cleared things up (didn't wait for the install to "finish") and tried re-installing 5.2.20. This is also now suffering this issue.

[Gordon Lack (gordon-lack)]

FYI: The 6.0 final installs OK. See:
   https://forums.virtualbox.org/viewtopic.php?f=7&t=90239#p436126
(and it worked for me...).

However, there IS still a BUG in systemd (which is where this bug should be moved - it isn't a virtualbox bug) as it shouldn't be possible for a package installation to crash systemd!

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

The `systemd` bug is reported and fixed upstream apparently (see bug-watch).

[Gianfranco Costamagna (costamagnagianfranco)]

should be fixed in the systemd in disco
