Migrating CentOS 8 to CentOS Stream 8

The CentOS Project announced today an end to a classic CentOS Linux as you know it, ending an era of CentOS as a RHEL rebuild. CentOS 8 will continue as a Stream version that you should upgrade to before the end of 2021. Here’s how.

First, if you missed it, here is the announcement by CentOS Project. And here is some more on how CentOS Stream will become the upstream of Red Hat Enterprise Linux.

If you are on CentOS 8, you should switch over to CentOS Stream 8 sooner or later. CentOS Stream should provide roughly the same system with the following differences:

To upgrade, install centos-release-stream package from extras repository:

$ sudo dnf install centos-release-stream

Is this ok [y/N]:

Then run dnf distro-sync:

$ sudo dnf distro-sync

The distro-sync subcommand is used to synchronize installed packages to the latest versions on upgrades. When no argument is provided, dnf updates all packages from active repositories.

And that’s it. You should be on CentOS Stream 8!

$ sudo cat /etc/centos-release
CentOS Stream release 8
