Comment 22 for bug 1825420

So, 4 weeks later, after my previous comments, and now running stably:

Upgraded to 5.0.0-15 today via command line with 'do-release-upgrade'. The triggers looping error still happens but this gets mopped up by dpkg --configure -a which the upgrade script autoruns for you.

The 'system error detected' pop-up was still there but I was able to cure this via:

https://gitlab.freedesktop.org/spice/linux/vd_agent/commit/098268a33c7c8008ccec9050aea8f0763f1c06d5

'/var/run' is a symlink but errors still happen; just edit out the '/var' prefix for the PIDfile entry in /lib/systemd/system/spice-vdagent.service.

I think this above is connected to the problems with virtual box too. Also edit the files /usr/lib/tmpfiles.d/spice-vdagentd.conf & speech-despatcher.conf while you are there. See 'cat /var/log/syslog' and you will see similar errors main spice one that's detailed.

VirtualBox itself upgraded without problem, as I was using the ubuntu packages this time. I just needed to editions, from file > prefs, to get get the machines to load up.

Don't think this was of significance, but who knows,so I probably should mention another couple of fixes I did before the upgrade, based on syslog entries:

This one here for OID file not found errors:

The other was commenting out 'max-height' and 'max-width' from gtk-widgets.css in /usr/share/themes/Ambiant-MATE/gtk-3.0. Annoying error that I have been meaning to sort out for a while now ...

I have tested this all day. Run it through its paces. Still a few little grumbles showing in the syslog but nothing serious I tend to think. I am guessing things trying to launch before AppArmor will let them, that's all.

Seems good.
