RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
When any rhscl package is installed on system, preupgrade-assistant suggest to add a repo as argument for the redhat-upgrade-tool-cli, which doesn't work:

#redhat-upgrade-tool-cli --network 7.0 --instrepo http://download.eng.brq.redhat.com/rel-eng/latest-RHEL-7/compose/Server/x86_64/os/ --addrepo optional=http://download.eng.brq.redhat.com/rel-eng/latest-RHEL-7/compose/Server-optional/x86_64/os/ --addrepo rhsclupg=http://download.lab.bos.redhat.com/rel-eng/RHSCL-1.1-RHEL-7-RC-1.0/
setting up repos... No upgrade available for the following repos: rhsclupg .treeinfo

One of the issues here is the fact that the provided address is not repository - although I think the error message from redhat-upgrade-tool could be more clear...

adding argument "--addrepo rhsclupg=http://download.lab.bos.redhat.com/rel-eng/RHSCL-1.1-RHEL-7-RC-1.0/compose/Server/x86_64/os" works for me

So the issue is with the error messages when provided repo is not a repo file and/or if there is a "conflicting name" used for the additional repository. And traceback when wrong number of arguments is provided.

Copying a commit from fedup to validate --addrepo so that an argument like --addrepo URL will print:

redhat-upgrade-tool: error: value should be REPOID=[@]URL

and exit, and adding a message "Check that the repo URLs are correct." after the "No upgrade available for..." line.

Verified on redhat-upgrade-tool-0.7.32-1.el6.
