Hello Pierre, thanks for bringing this up and for the investigating the right certificate! I think this time I got the right CA chain, could you check again?
Also note that all packages are available also on cvmrepo.web.cern.ch (browseable mirror on eos) and cvmrepo.s3.cern.ch (direct link to s3). I’m recommending to use
yum install -y https://cvmrepo.s3.cern.ch/cvmrepo/yum/cvmfs-release-latest.noarch.rpm
or
wget https://cvmrepo.s3.cern.ch/cvmrepo/apt/cvmfs-release-latest_all.deb
sudo dpkg -i cvmfs-release-latest_all.deb
in production.
Cheers,
Valentin
