I am trying to setup on a new box following the guide, everything seems to run OK but when I try to check the config or or do the probe ect I get the following:

Error: failed to load cvmfs library, tried: './libcvmfs_fuse3_stub.so' '/usr/lib/libcvmfs_fuse3_stub.so' '/usr/lib64/libcvmfs_fuse3_stub.so' './libcvmfs_fuse_stub.so' '/usr/lib/libcvmfs_fuse_stub.so' '/usr/lib64/libcvmfs_fuse_stub.so'

Failed to read CernVM-FS configuration

Any ideas? OS is Linux mint 21

Not sure what you mean, I followed the guide listed there and get the errors I posted above? I don't see anything specific in that linked post that's different to what I have already followed?

This computer reported valid native tasks yesterday:
https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10804831


Is your computer having CVMFS issues already listed here (most likely not)?

The error messages tell you that some required libs are not installed (or your OS doesn't find them).
Did you use the same installation package you used for host 10804831?
Did you restart the computer after installation?

The OS was updated, during the update process it seemed to remove all the cvmfs stuff so I am trying to reinstall everything

I have checked and it looks like the files its looking for are there

Did you install and activate the automounter service?

check with:
systemctl status autofs

I have tried a fresh install of the OS and still getting the same issue.
Output from is systemctl status autofs

I am following this guide https://cvmfs.readthedocs.io/en/stable/cpt-quickstart.html

Next step would be to find out if/where your CVMFS installation/configuration is broken.

You did not yet answer the question whether you used an installation package or compiled the software yourself.
In case of a package, which one did you use?

Did you also use the most recent cvmfs-config package?


After installation completed, reboot, then run:
ldd $(command -v cvmfs_config)
ldd $(command -v cvmfs_talk)

In case of any errors, post them.


No errors, continue with:
cvmfs_config showconfig -s atlas

Post the output here.


Hint:
Depending on your global Linux configuration some of the commands above may need to be prefixed by "sudo ", e.g. "sudo cvmfs_config ...".


BTW:
The forum editor allows you to mark a string as link using the "url" tag.
Would be nice if you could use this feature.

Ok I have gone back to 2.03 and all is now working fine, maybe an issue with the latest distro?

One thing I am now struggling with and cant find the post that helped me before, is with setting up a app_config file to limit the number of tasks that are run at the same time, I keep getting this error

LHC@home: Notice from BOINC
Your app_config.xml file refers to an unknown application 'Theory'. Known applications: 'ATLAS'

Sorted, it was case sensitive.

Has anyone else had this issue with the latest release of Mint / Ubuntu?

Has anyone else had this issue with the latest release of Mint / Ubuntu?

I used Apptainer on a new Ubuntu 20.04.4 installation a month ago with no problem.
