1) Message boards : Theory Application : Theory native fails with \"mountpoint for cgroup not found\" (Message 47799)

I am getting this same/similar issue on my Ubuntu 22.04 LTS Virtualbox. Can someone describe how to upgrade the runc version, and/or if this is a valid fix that doesn't cause data processing errors?

Due to this error I have tried to follow instructions to install the CernVM-FS service with little success.

This was the initial task error:
[2023-02-20 02:41:25] Checking for CVMFS
[2023-02-20 02:41:25] No cvmfs_config command found, will try listing directly

[2023-02-20 02:41:25] ** and setting 'CVMFS_REPOSITORIES=atlas.cern.ch,atlas-condb.cern.ch' in /etc/cvmfs/default.local
02:41:26 (5392): run_atlas exited; CPU time 0.015609
02:41:26 (5392): app exit status: 0x1



**UPDATE: It looks like everything is up and running for cvmfs after receiving an "OK" confirmation from the 
sudo cvmfs_config chksetup
command. I will followup if further issues.
3) Questions and Answers : Unix/Linux : Install of AlmaLinux9 (Message 47771)
Posted 20 Feb 2023 by wanderphx
Post:
Does anyone have experience installing AlmaLinux9 on VirtualBox (or any experience at all)?

I am having difficulty installing required files on my Umbuntu VirtualBox to fix an error so I'd like to try AlmaLinux9 but am having trouble getting hold of a disk image. The following link begins to download but then stops with an error:
https://linuxsoft.cern.ch/cern/alma/9/BaseOS/x86_64/os/images/boot.iso

The closest instructions I have found to install Alma9 was here (where I found the boot.iso link):
https://linux.web.cern.ch/almalinux/alma9/install/
And here (but I can't figure out how to login to openstack.cern.ch):
https://linux.web.cern.ch/almalinux/

Any suggestions (even an alternative) for linux on VirtualBox is welcomed.

Thanks! I thought I had vm turned on for AMD (SVM) in bios but I forgot I reset the bios a couple months back. I enabled svm and ATLAS simulation is working great so far!

I often get a "computation error" when running LHC tasks on vm. Has anyone any suggestions on how to troubleshoot the issue?

Here is my setup: https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10821098
