I thought I would share my version of how I updated the server that runs this blog from Rocky 8 to Rocky 9 without a clean install. I want to mention this is a do at your own risk post, this is not officially supported.
!!!Do not attempt this if you do not have backups and a way to fully recover your system.!!!
The first step I took was go to the rocky download site and make sure I grabbed the latest GPG, RELEASE and REPOS:
https://download.rockylinux.org/pub/rocky/9/BaseOS/x86_64/os/Packages/r/
You will need to modify the below command to match the version you find in the above site, once that is complete you can run it.

[root@rocky-us-east-jasonralph ~]# dnf install -y https://download.rockylinux.org/pub/rocky/9/BaseOS/x86_64/os/Packages/r/{rocky-gpg-keys-9.2-1.4.el9.noarch.rpm,rocky-release-9.2-1.4.el9.noarch.rpm,rocky-repos-9.2-1.4.el9.noarch.rpm} |
One road block was dnf did not like that I had remi and epel release 8, so I removed them and it went fine.

Find the epel and remi release rpms:
|
1 2 3 4 |
[root@rocky-us-east-jasonralph ~]# rpm -qa| grep release remi-release-8.7-2.el8.remi.noarch epel-release-8-19.el8.noarch rocky-release-8.7-1.2.el8.noarch |
Remove them:
|

[root@rocky-us-east-jasonralph ~]# yum remove epel-release-8-19.el8.noarch remi-release-8.7-2.el8.remi.noarch |
Upgrade your system to 9 from 8:
|

[root@rocky-us-east-jasonralph ~]# dnf install -y https://download.rockylinux.org/pub/rocky/9/BaseOS/x86_64/os/Packages/r/{rocky-gpg-keys-9.2-1.4.el9.noarch.rpm,rocky-release-9.2-1.4.el9.noarch.rpm,rocky-repos-9.2-1.4.el9.noarch.rpm} |
I ignored this error, it seems like its just a GPG error:
|

Verify:

[root@rocky-us-east-jasonralph ~]# cat /etc/rocky-release Rocky Linux release 9.2 (Blue Onyx) |
Rebuild the RPM database to now use SQLITE:
|
1 |
[root@rocky-us-east-jasonralph ~]# rpm --rebuilddb |
Thats it, reboot:

[root@rocky-us-east-jasonralph ~]# reboot |
I did have some issues with dnf where I needed to reset some modules.

[root@rocky-us-east-jasonralph ~]# dnf check Modular dependency problems: Problem 1: conflicting requests - nothing provides module(platform:el8) needed by module httpd:2.4:8070020230406163027:3b9f49c4.x86_64 Problem 2: conflicting requests - nothing provides module(platform:el8) needed by module mariadb:10.3:8060020220913075833:d63f516d.x86_64 Problem 3: conflicting requests - nothing provides module(platform:el8) needed by module mysql:8.0:8060020221025174942:d63f516d.x86_64 Problem 4: conflicting requests - nothing provides module(platform:el8) needed by module nginx:1.14:8040020210610090123:9f9e2e7e.x86_64 |
I needed to reset the modules one by one, there may be more on your system:
|
1 |
[root@rocky-us-east-jasonralph ~]# dnf module reset httpd:2.4 mariadb:10.3 mysql:8.0 nginx:1.14 |
That seemed to fix it, good luck.
