If you're trying to migrate from RHEL to OL you should follow steps public available at https://linux.oracle.com/switch/ . Let us know if it works or not. Thanks

It does not, because it requires an UNL subscription and account. It seems even a paid Oracle Cloud account can't use that step and can't even create a new UNL account.

scoter-oracle commented 7 months ago

So, the solution proposed here is to migrate CentOS (7 or 8) to the correspondent Oracle Linux release. That said, there's the solution to switch from RHN to ULN. It seems that your use-case is not covered by those two options; what I can do is to just suggest those steps (to see if those work):

Disable RH Network Yum repositories by

# dnf config-manager --disable

Download .repo file for OL9 with

# wget https://yum.oracle.com/mirror/ol9/x86_64/oracle-linux-ol9-x86_64.repo -O /etc/yum.repos.d/oracle-linux-ol9-x86_64.repo

Download GPG keys for Oracle Linux Yum Server

# wget https://yum.oracle.com/RPM-GPG-KEY-oracle-ol9 -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle # gpg --quiet --keyid-format 0xlong --with-fingerprint /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle

Try to update your system with "dnf update --allowerasing"

On (2) you usually need to enable repositories like "ol9_baseos_latest" and "ol9_appstream". Please note that this is not an official process but just a suggestion on how you could get your system leveraging OL updates from yum.oracle.com website.

@scoter-oracle Just to be clear, can you give guidance on what commands should be used for or whether it is on by default: you usually need to enable repositories like "ol9_baseos_latest" and "ol9_appstream".

Thank you.

scoter-oracle commented 7 months ago

You can edit the /etc/yum.repos.d/oracle-linux-ol9-x86_64.repo file and enable the channels you need/want for OL9.

digirave commented 7 months ago

@scoter-oracle Thank you. Of note, I asked because in https://yum.oracle.com/mirror/ol9/x86_64/oracle-linux-ol9-x86_64.repo "ol9_baseos_latest" and "ol9_appstream" are enabled by default.

I do hope that Oracle officially supports migration from RHEL to Oracle Linux without a ULN subscripton in the future, because basicially even testing migration will require buying Oracle Linux subscription at this time, which will definitely hinder people from even testing. I do think the above works somewhat, but is only a partial conversion. For example it doesn't remove the RHEL subscription checks that run each time dnf is run which seems very bad.

Just a note to anyone looking for information:

Conversion from RHEL 9.3(current latest) to Almalinux works the best, it can be done with or without being registered to redhat subscription, Almalinux conversion script seems to be "cleanest" in multiple workflows I tested
Conversion from RHEL 9.3(current latest) to Rocky linux works, only if you are registered and subscribed to redhat, if not subscribed the conversion tool will not work
Conversion from RHEL 9.3(current latest) to Oracle linux will not work properly without a valid UNL subscription, and doing it manually with above steps in comments seems to do a unclean conversion, and I would suggest converting to something supported by the official Oracle conversion tool such as Rocky linux and then converting to Oracle linux if conversion is absolutely needed from RHEL to Oracle Linux.

Thanks for your feedback @digirave
