Bonjour,
Toutes les WU partent systématiquement en erreur au bout de quelques minutes.
Une idée ?
Bonne journée.
Bruno.

We can't see your computer and the failed tasks. You need to set "Preferences for this project LHC@home preferences" -> Should LHC@home show your computers on its web site?

The logs of the tasks usually show where it failed.

Oups, c'est bon maintenant.

An exemple :

<core_client_version>8.2.9</core_client_version>

On your host create an empty directory '/cvmfs' and set the permissions to 777.

[sudo] mkdir /cvmfs
[sudo] chmod 777 /cvmfs

How to ?
I am on MacOS Sequoia

Since Catalina 10.15 (introduced in 2019!) the root filesystem is read-only.
To fake a subfolder there you may need an entry in /etc/synthetic.conf that looks like this:
cvmfs<tab>System/Volumes/Data/cvmfs

After a reboot /cvmfs should be available for the Theory docker app.
For more info see:
https://keith.github.io/xcode-man-pages/synthetic.conf.5.html

Since I don't have a Mac I can't verify this method, so please post a comment whether it worked or not.
To check the logs it would be good that you make your computers visible in the prefs:
https://lhcathome.cern.ch/lhcathome/prefs.php?subset=project

Permission denied to create the file synthetic.conf on the directory /etc/

When you install a local CVMFS on MacOS this is what 'cvmfs_config setup' originally does (copied from the CVMFS source code):

     # Since MacOS 10.15 Catalina it is not possible anymore (without disabling
     # SIP) create directory in root `/`.
     # We decide to move the standard installation directory on
     # `/Users/shared/cvmfs` instead of `/cvmfs`
     # In order to keep the standard CVMFS mountpoint, we decide to implement
     # firmlinks from `/cvmfs` to `/Users/shared/cvmfs`
     if compare_versions $(sw_vers -productVersion) -ge "10.15"; then
        mkdir -p /Users/shared/cvmfs
        chown cvmfs:cvmfs /Users/shared/cvmfs
        chmod 777 /Users/shared/cvmfs
        if ! grep -q "^cvmfs\t" /etc/synthetic.conf 2> /dev/null ; then
          echo -e "# The line below was autogenerated by CernVM-FS, do not delete nor edit" >> /etc/synthetic.conf
          echo -e "cvmfs\t/Users/Shared/cvmfs" >> /etc/synthetic.conf
        fi
        # reload synthetic.conf - seems to return nonzero status code even on success
        /System/Library/Filesystems/apfs.fs/Contents/Resources/apfs.util -t || true
     else
        echo "Fuse4x and autofs bug" > /dev/null
        mkdir -p /cvmfs
        chown cvmfs:cvmfs /cvmfs
        chmod 777 /cvmfs
     fi

To run Theory (docker) without a local CVMFS you MUST ensure '/cvmfs' is present since the container requires it as mountpoint.
So, manually run the relevant commands from the source code above as admin, then reboot:

mkdir -p /Users/shared/cvmfs
chmod 777 /Users/shared/cvmfs
if ! grep -q "^cvmfs\t" /etc/synthetic.conf 2> /dev/null; then echo -e "cvmfs\t/Users/Shared/cvmfs" >> /etc/synthetic.conf; fi

The part between 'if' and 'fi' must be run as one command without a newline that may be inserted by the forum software here!
If you get permission issues you may not be admin!
In this case, consult your manual or visit MacOS related websites.
