Error building O2Physics in Ubuntu 20.04.6 LTS

Dear all,

After updating alidist and O2, i tried building O2Physics, but I get the error message

Hi @sinese, there’s a conflicting ROOT installation in /home/sigurd/root that’s confusing aliBuild. Please remove it from your environment or delete it!
