LHC@home

I recently upgraded to Ubuntu 22.04 Unity and successfully installed BOINC, lhc@home project + others, and the cvfms file system. Each project appears to be working properly yet all lhc@home ATLAS Simulation v3.01 (native_mt)x86_64-pc-linux-gnu tasks are reporting "Computation error" and "195 (0x000000C3) EXIT_CHILD_FAILED".

Examples:

https://lhcathome.cern.ch/lhcathome/result.php?resultid=419694154

The other three projects I run, Asteroids@home, Einstein@home, and Rosetta@home, all process work units successfully to completion and validation.

BOINC ver: 8.0.2
OS ver: Ubuntu 22.04 Unity
Linux kernel: 5.15.0-131-generic
Virtualbox (6.1.40r154048) installed, CPU has hardware virtualization support and it is enabled.
cvmfs ver: 2.12.6~1+ubuntu22.04 (cvmrepo.s3.cern.ch) Jakob Blomer <jblomer@cern.ch>

:~$ groups boinc
boinc : boinc video render vboxusers

User group assignments, permissions and cvmfs config have been reviewed and appear to be correct.

One lhc@home err reported consistently is:

ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded: ignored.

Fully qualifying the executable path name for libgtk3-nocsd.so.0 to "/usr/lib/x86_64-linux-gnu/libgtk3-nocsd.so.0" when assigned to LD_PRELOAD does not eliminate this err.

The other notable err occurs following a cvfms/.../apptainer command:

[2025-02-19 14:01:34] Running command: /cvmfs/atlas.cern.ch/repo/containers/sw/apptainer/x86_64-el7/current/bin/apptainer exec -B /cvmfs,/var/lib/boinc/slots/7 /cvmfs/atlas.cern.ch/repo/containers/fs/singularity/x86_64-centos7 sh start_atlas.sh
[2025-02-19 14:04:46] Job failed

Only one Theory Simulation v300.08 (native_theory) has completed and validated successfully. Most other ATLAS Simulation v3.01 (native_mt) (once cvmfs installation complete) have failed with all reporting "Computation error" and "195 (0x000000C3) EXIT_CHILD_FAILED".

Suggestions?

At least 1 of your logfiles report:

[2025-02-20 05:50:09] Checking for apptainer binary...
[2025-02-20 05:50:09] apptainer is not installed, using version from CVMFS

Please try a local apptainer package from your Linux vendor.

Keep in mind that ATLAS does not support suspend/resume and Theory does not support it on your system due to missing requirements (see the logs).

In addition, although it works your CVMFS configuration seems to be incomplete.
