Dear Narcis, I see these two independent errors:
> E:The repository 'http://ppa.launchpad.net/ubuntugis/ppa/ubuntu bionic > Release' does not have a Release file., > [...] > E:The repository 'https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/ > InRelease' is not signed."} The first repository (ubuntugis) is not part of what ElastiCluster provides -- maybe it was added by a colleague of yours? The second repository (bionic-cran35) is what is used to install R -- I'll check if they have changed the signing key. Ciao, R -- You received this message because you are subscribed to the Google Groups "elasticluster" group.
