Bug 1726712

Description of problem:
Versionlock in yum used to allow us to upgrade a previous version of the package.  For example, if we had puppet agent 6.4.2 installed, and versionlocked at 6.4.2, we could then update the versionlock to 6.5.0 and then yum upgrade puppet-agent and that would work.  dnf, on the other hand, appears to lose all knowledge that there is or ever was puppet-agent 6.4.2.  Basically it claims there is nothing to upgrade.  It would let me install puppet agent 6.5.0, but it treats it like there is nothing to upgrade and just layers things on top.  Strangely, I can work around this by manually adding BOTH 6.4.2 and 6.5.0 locks to versionlock.list, but that's not particularly sustainable.

Please note that I use the puppet yum module to handle versionlocks, which adds entries to versionlock.list rather than using the dnf commands.  However, I believe that is considered a perfectly legit means of maintaining that file.

Version-Release number of selected component (if applicable):
4.0.9.2

How reproducible:
I can easily reproduce with the steps below

Steps to Reproduce:
1. add to /etc/dnf/plugins/versionlock.list: puppet-agent-0:6.4.2-1.el8.x86_64
2. install puppet-agent 6.4.2
3. replace the line from step 1 with: puppet-agent-0:6.5.0-1.el8.x86_64
4. dnf upgrade puppet-agent-6.5.0

Actual results:
Package puppet-agent available, but not installed.
No match for argument: puppet-agent-6.5.0
Error: No packages marked for upgrade.

Is this ok [y/d/N]:


Additional info:
I don't know that this isn't intended behavior, but it worked very cleanly with yum in RHEL 7 and make for some easy ways to handle puppet-led upgrades.  And of course -- if you go to reproduce the expected behavior on RHEL7, make sure to replace el8 with el7 in your lock.  =)
