conversion from centos 7 to RH 7 fails [HTTPS Error 404 ]

[snash4]

Hi,
I am trying to convert my cento7 to RH 7 using convert2rhel tool.
It fails to find mirror:
https://cdn.redhat.com/content/dist/rhel/server/7/8.1/x86_64/os/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found

fails at running this command:

Hi @snash4, it looks like the 8.1 was for some reason hardcoded in the baseurl of the rhel-7-server-rpms repoid on your system, before you executed convert2rhel. So it seems you have pre-registered the system, isn't it so?

I can imagine you could have got to the situation by running the following command on the CentOS 7 machine that would "break" the URL of the repository:
subscription-manager release --set 8.1
If you did that, you can undo it by subscription-manager release --unset.

If not, you can verify whether my assumption of a hardcoded releasever is correct by looking into /etc/yum.repos.d/redhat.repo. Under [rhel-7-server-rpms] you should have $releasever in:

baseurl = https://cdn.redhat.com/content/dist/rhel/server/7/$releasever/$basearch/os

I advise you creating a support case at https://access.redhat.com/support to get a timely response. We have great support folks who know the conversion process and can help you further troubleshoot the issue.
