Got this problem when doing a regular "Update/upgrade" from shell

/usr/bin/deb-systemd-invoke: 39: Syntax error: newline unexpected

Endless loop of these two lines in bash before the crash.

you seem to have some problem with /usr/bin/deb-systemd-invoke, which is a perl script, but it seems to be getting called by /bin/sh. You should try reinstalling init-system-helpers to fix any problem with your script, and/or if you made any changes yourself manually that may be causing the problem.

$ sudo apt --reinstall install init-system-helpers

[Stefan von straten Finne (oden99)]

Looks like the reinstall with the system helpers did the trick. The
package now installed and seems to work as intended.

I did some cleaning and I don't have any package problems hanging around
any more. So I would think it is a solved problem now.

Thank you for the support.

Thanks for the feedback Stefan (and the Help Dan).
I'll mark the bug as invalid then as there is nothing to fix in a package for it.
