Post Install very little in the GUI works

[jaredh]

I have two servers I have upgraded from 11.SP4 to 15 running in Hyper-V. Both of them are exhibiting this problem.

The issue I am running into is essentially all Gnome applications are broken. Terminal and Files work, but no Yast module works, Firefox, Wireshark, Yast2 crash, etc.

Here are some of the errors I see:

Wireshark and Yast2 run from a command line fail with:

wireshark.desktop[5160]: /usr/bin/wireshark: symbol lookup error : /usr/lib64/libQt5XcbQpa.so.5: undefined symbol: FT-Get_Font_Format

Firefox fails with the following:

firefox.desktop[5232]: XPCOMGlueLoad error for file /usr/lib64/firefox/libxul.so:
firefox.desktop[5232]:/usr/local/lib/libz.so.1: version 'ZLIB_1.2.9' not found (required by /usr/lib64/firefox/libxul.so)
firefox.desktop[5232]: Couldn't load XPCOM

rpm -qa | grep zlib shows:

zlib-devel-1.2.11-1.422.x86_64 is installed

Running yast modules from the Gnome interface creates these errors

gnomesu-pam-packend[5293]: pam_systemd(gnomesu-pam:session): Cannot create session: Already running in a sesson
YaST2-timezone.desktop[5285]: terminate called after throwing an instance of 'YUIPluginException'
YaST2-timezone.desktop[5285]: what(): Couldn't load plug-in qt

libyui-qt8-2.49.2-1.30.x86_64 is installed on these systems.

I'm currently at a loss. I've check the repositories and I believe they are correct. These are the 2 I believe should be Enabled and they are:

SLE-Module-Basesystem15-Pool
SLE-Module-Basesystem15-Updates

I ran an forced zypper update and dup and nothing will currently download on these servers indicating they are up-to-date.

Did the installer bork these systems somehow and what ideas does anyone have to correct it?
