Software repositories

Install software repository definitions on your previously-installed non-CERN RHEL8 system, by running as root:

You may also want to consider adding the 'CERN' repository

# curl -o /etc/yum.repos.d/rhel7-cern.repo https://linux.web.cern.ch/rhel/repofiles/rhel7-cern.repo
# curl -o /etc/pki/rpm-gpg/RPM-GPG-KEY-kojiv2 https://linuxsoft.cern.ch/internal/repos/RPM-GPG-KEY-kojiv2

Direct download: rhel7.repo.

To update your system run as root:

# /usr/bin/yum update
