The ROOT team shares some interesting news about ROOT docker images in this brand new blog post . Cheers, Enrico

I pushed all the root images in /cvmfs/unpacked.cern.ch which means it is possible to do on lxplus: singularity exec /cvmfs/unpacked.cern.ch/registry.hub.docker.com/rootproject/root:6.22.00-ubuntu20.04 root To get a running instance of the latest root. Cheers, Simone
