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
======================

`--list-contents-set` is useless: uf more than one upgrade path is present,
it will not list anything (it will only *say* there are more).

    # preupg --list-contents-set
    Preupgrade assistant detects more then 1 set of contents in directory/usr/share/preupgrade. If you would like to use this tool, you have to specify correct upgrade path parameter like -s RHEL6_7.
    #


Version-Release number of selected component
============================================

preupgrade-assistant-2.1.6-5.el6


How reproducible
================

Always


Steps to Reproduce
==================

 1. Put an upgrade path in /usr/preupg/ (eg. make copy of existing one,)
    but mind that naming must be `FOO<M>_<N>`
 2. `preupg --list-contents-set`
 3. observe list of upgrade paths


Actual results
==============

There is none.


Expected results
================

There should be two upgrade paths.

This is fixed by upstream commit https://github.com/upgrades-migrations/preupgrade-assistant/commit/ebb87ca8317ffc182ef87dc054736c9e6dfda40e

Thanks for clarification.

As of preupgrade-assistant-2.1.9-5.el6:

    # cp -r /usr/share/preupgrade/RHEL6_{7,8}
    # preupg --list-contents-set
    RHEL6_7
    RHEL6_8
    #

IOW, issue is fixed.
