Hello, So I was trying to install kolab 3.3 on a CentOS 7 vm. yum can't proceed because: "Public key for kolab-conf-3.1.8-4.2.el7.kolab_3.3.noarch is not installed". Usually with a yum repo there is a repo-release.rpm file which includes the gpg key in the rpm and the in the .repo file installed in /etc/yum.repos.d/ Where is the gpg key? -- Nathanael
