[Matthew D. Mower (mdmower)]

I reinstalled Ubuntu GNOME (I had barely started on a fresh installation when this issue arose), and installed openvpn first thing. Installation succeeded without issue. I won't be able to reproduce this issue, so feel free to mark it 'invalid'.

[Andreas Hasenack (ahasenack)]

Unfortunately the attached logs don't help much. A full ps output, like ps fauxw, would have perhaps shown in more detail what was going on, which process called what, etc.

I'll mark this bug as incomplete for now. If it happens again, feel free to update it. Otherwise, it will expire on its own after a while.

Thanks!

I am also experiencing this bug on a system installed last night. I got a hang while running 'apt install network-manager-openvpn-gnome', gave up and killed the process, and I am now getting a hang again while running 'dpkg --configure -a'.

'ps fauxw' seems to indicate that the post-install script is waiting on 'plymouth --ping'. And indeed if I run that command separately, it does not return.

[Alexander Lasley (lasleyaj)]

This appears to be fixed with the latest version of the plymouth package. It turns out my system was not entirely up-to-date when I tried to install network-manager-openvpn-gnome.

For those who make it here from a search engine, you can make the post-install script complete by finding the pid of 'plymouth --ping' and killing it. The script will retry a few times but give up eventually. Then you should be able to get back to a state where you can upgrade the rest of your packages before retrying this one.

[Expired for openvpn (Ubuntu) because there has been no activity for 60 days.]
