Does anyone have an idea what causes this, and how to fix it?

Let me know if more details are required.

It seems that leapp is having trouble parsing one of your configuration files for named. I was unable to reproduce the issue with the '/etc/named.conf' file from the feedback archive. Therefore, I believe the issue may be in the '/etc/named-user-options.conf' file, as it is the only included configuration file. Could you please share the '/etc/named-user-options.conf' file with me so that I can continue the investigation?

[MIJmker]

Hi, thx for checking. That file is empty however

[SandakovMM]

Oh, I understand. This is the cause of the problem. To resolve it, you need to add the following content to the file:

version "none";
auth-nxdomain no;
listen-on-v6 { any; };

Alternatively, you could simply remove the include "/etc/named-user-options.conf"; directive from the /etc/named.conf file.

I will solve the problem, likely by adding a prechecker. Additionally, I think the issue may have already been fixed on the elivate side, but I'm not certain. I will investigate further when we release the new version of centos2alma, where we plan to upgrade to the latest version of elivate.

Thanks, that seems to fix it (removing include of that file). The pre-upgrade error was gone so I migrated it and still have a database issue, but if I can't figure it out myself I'll open another ticket.

I'll close this one. Thanks for your help
