Univention Bugzilla – Bug 47808
New firefox 60.2.0esr-1~deb9u2 breaks UCS installation and Appliance Tests
Last modified: 2018-09-26 13:24:49 CEST
The installer starts but after installing the base system, i get a black screen (UMC setup expected at this point)
i see lots of these message
GFX1: Failed to lock new back buffer.
All installation tests are broken until this is fixed.
Firefox works as expected after i reboot the machine, so i guess the appliances are not affected.
The problem is that /dev/shm isn't created and mounted with tmpfs.
I can reproduce that firefox works again with a mounted /dev/shm.
Afaik it is mounted through /usr/lib/tmpfiles.d/debian.conf which is handled by systemd which is not active in the debian installer.
Firefox 52esr doesn't seem to need /dev/shm.

app appliance setup
Also, the "do not show tabs" plugin seems to be broken now, this breaks the app appliance tests.
i have de-activated the UCS 4.3-2 Install Tests, please re-activate if this is fixed.
