Convert Centos 8 to Centos 8 Stream

sandeep

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

dnf install centos-release-stream
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!

cat /etc/centos-release
CentOS Stream release 8

@sandeep Hello!

Are we in any danger when using these commands?

Should we take something into account before doing the conversion?

Greetings!

@sandeep I just tested on a centos 8 server with CWP and got these errors:

[root@vps ~]# dnf distro-sync
CentOS-Stream - AppStream 20 MB/s | 6.3 MB 00:00
CentOS-Stream - Base 602 kB/s | 2.3 MB 00:03
CentOS-Stream - Extras 8.0 kB/s | 7.0 kB 00:00
Error:
Problem: package libgs-devel-9.25-7.el8.x86_64 requires libgs(x86-64) = 9.25-7.el8, but none of the providers can be installed

(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

@josepp backup is must when you're doing major upgrades. Since CWP will not support centos 8 anymore the recommended version is centos 8 stream.
