I wanted to setup a new Sytem for Atlas Native with Ubuntu 22.04.1

Somewhere I had seen several questions about is Apptainer / cvmfs working with Ubuntu 22.04.1, but never found an answer.

So I have upgraded a working machine to Ubuntu 22.04.1 and for me, it looks as if all is working fine.

cvmfs tells ok
apptainer tells ok
Hitfile is produced

So, is there more that I should check ?

Or, can someone check my results from this box: https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10813571

Thanks in Advance

Supporting BOINC, a great concept !

In Production is singularity active and multiattach.
Only in -dev is apptainer in use, but there is no new work (Holiday?).

Looks fine.

The most important log entry is:
HITS file was successfully produced

Beside that there are no obvious errors at the beginning of the log.
Nonetheless, if you occasionally see failed/invalid tasks with runtimes of just a few minutes you may check whether they also fail on your wingcomputers.

From the logfile in production:

The check for the command is here:
2022-08-30 06:15:06] Running /usr/bin/singularity --version

It returns:
[2022-08-30 06:15:06] apptainer version 1.1.0-rc.2

This means your system is running Apptainer.



The line:
[2022-08-30 06:15:06] Singularity works
is a hardcoded String that the script prints to the log.

It could also print "Wuppdibragglkennsdmined works" and it would still run Apptainer.



On -dev David tests an updated script that prints the hardcoded string "apptainer works".


ATM " /usr/bin/singularity" and " /usr/bin/apptainer" start the very same program but since the name "singularity" will sooner or later disappear all scripts using it need to be modified to use "apptainer".


Regarding the lack of tasks on -dev.
Yes they are intentionally very small and for testing the process rather than for productive work.

[2022-08-30 06:15:06] Singularity works
is a hardcoded String that the script prints to the log.

It could also print "Wuppdibragglkennsdmined works" and it would still run Apptainer.

But hopefully it prints this only to the log if it really works

@David Cameron:
I have reverted back to v2.87. Many tasks were failing with errors creating temporary files like this:
Failed to execute payload:mktemp: failed to create file via template '/tmp/asetup_XXXXXX.sh': Read-only file system
which may be related to the change in the way directories are mounted in the container. I'm investigating.

In English it's the same name "Kindergarten".
