In this tutorial we’ll Convert Centos 8 to Centos 8 Stream and install CWP control panel in it. It is pretty easy to convert centos 8 to stream just follow few basic steps and you’re ready to go.

Since CWP Declared that it will fully support centos 8 stream edition and Dependencies are maintain by CWP repo i.e. you didn’t need to worry about stability of the OS it will provided delayed updated via there own repo and its a good news, obviously you’ve option to select there repo and stream base repo for delayed updates and regular updates respectively.

Without wasting too much time let get started . Ensure you’ve install centos 8 on your server if it is not stream edition then convert it via this commands :

**if CWP is already installed just follow Step 1, Step 3 and Step 4

Step 1

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

dnf install centos-release-stream
dnf swap centos-{linux,stream}-repos
mv /etc/yum.repos.d/CentOS-AppStream.repo /etc/yum.repos.d/CentOS-AppStream.repo.bak  
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak  
rsync -av /etc/postfix/ /etc/postfix.bak/
dnf module disable postfix
rpm -e --nodeps qt5-qtbase qt5-qtbase-common qt5-qtbase-gui
sed -i 's/enabled=0/enabled=1/g' /etc/yum.repos.d/CentOS-Stream-PowerTools.repo  
dnf distro-sync 

**if you see “No such file or directory” during “mv” command execution ignore that same for “error: package qt5-* is not installed” can be safely ignored

*** rsync -av /etc/postfix/ /etc/postfix.bak/ it will backup postfix dir

If you get error after running “dnf distro-sync” then just run this two commands :

dnf clean packages
dnf update

If you still have issue then run update with nobest then allowerasing pipe :

dnf clean packages
dnf update --nobest
dnf update --allowerasing

After that you’ll see upgrading process is now started wait for the upgrade completion, then check the Centos version via this command :

cat /etc/centos-release

eg :

[root@mysterydata ~]# cat /etc/centos-release
CentOS Stream release 8
