Hi,

I'll say first that I am a bit of a newb when it comes to Linux, I did manage to get CVMFS setup and confirmed working however the apps seem to be failing out with this error:

"FATAL: container creation failed: hook function for tag prelayer returns error: failed to create /var/lib/alternatives directory: mkdir /var/lib/alternatives: permission denied"

Any idea what I missed?

WU as an example:

Thanks in advance

This is the main issue:
[2022-02-10 06:43:50] Checking for singularity binary...
[2022-02-10 06:43:50] Singularity is not installed, using version from CVMFS

You may need to install a recent Singularity package from your Linux repositories.


Be aware that your ATLAS uses 12 threads during the main calculation phase but only 1 thread during setup and stage out.
Setup can take up to 30 min and inexperienced users may think the task is idle.

Since you are running Linux Mint 20.3 which is derived from Ubuntu 20.04 you may check this links:
