TB not starting after Upgrade

Description

After upgrading Ubuntu 22.04 to 24.04.1 TheocBase doesn’t start anymore.

When starting theocbase.sh it tells:

$ ./theocbase.sh -h
MESA-LOADER: failed to open iris: /usr/lib/dri/iris_dri.so: Kann die Shared-Object-Datei nicht öffnen: Datei oder Verzeichnis nicht gefunden (search paths /usr/lib/x86_64-linux-gnu/dri:$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)

The solution:
look at the error message, when you run /opt/TheocBase/theocbase.sh from the command line.
In my case the file iris_dri.so could not be found

update your files database: updatedb
locate the file in your system: locate iris_dri.so
it was located in /usr/lib/x86_64-linux-gnu/dri/iris_dri.so

put a LD_PRELOAD before the TB start in the file /opt/TheocBase/theocbase.sh:

replace the line

$dirname/AppRun --no-sandbox $*

with this:

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/dri/iris_dri.so $dirname/AppRun --no-sandbox $*

save the script and TB should now run again.
