While executing the below command, encountered the error “Unknown repo crb“.
# dnf --enablerepo=centos-openstack-yoga,epel,crb -y install openstack-glance Error: Unknown repo: 'crb'
Solution: CRB is known as CodeReady Linux Builder. However, it is trademarked, and as such, available only in CentOS which has a different name – PowerTools. The PowerTools repository provides most of the developer tools required by many EPEL packages. Disabled by default
Install the EPEL release package for CentOS Stream 8. Enable both the EPEL and CodeReady Builder repositories as below:
# dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm -y # /usr/bin/crb enable Enabling CRB repo CRB repo is enabled and named: powertools
# sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-* # sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-* # dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm -y # dnf config-manager --set-enabled powertools
Now use the renamed repo name in your
dnf installation as below:
# dnf --enablerepo=centos-openstack-yoga,epel,powertools -y install openstack-glance
