Comment 1 Miro Hrončok 2018-07-23 09:11:12 UTC 
The root of this problem is:

"python3-modulemd-1.3.3-1.fc28.noarch requires python(abi) = 3.6"

This drags 3.6 and prevents you to update to 3.7.

modulemd was retired from Fedora and hence a newer version, that would use Python 3.7, is not available.

Retirement commit:  https://src.fedoraproject.org/rpms/modulemd/c/670430593aa493f80e283db13b195d6ff2d2cbf0?branch=master

It says:

> The package is obsolete and effectively replaced with (incompatible) libmodulemd


While libmodulemd obsoletes (on RPM level) nothing.


It used to obsolete python3-modeulemd:

https://src.fedoraproject.org/rpms/libmodulemd/c/b8df168786ad93f2645632c19c28f3b7e085b134?branch=master


Yet it was reverted (no reason obvious from the commit message):

https://src.fedoraproject.org/rpms/libmodulemd/c/5c87b190bce73ad3f6a2801da107ac495c546a10?branch=master


libmodulemd maintainers, please:

 - obsolete pythonX-modulemd from libmodulemd or fedora-obsolete-packages (you can provide this bugreport as the reason).

 - provide a reason why the obsoletes were removed
Comment 2 Jun Aruga 2018-07-23 10:01:40 UTC 
Thanks for the quick response.
I still do not understand the root reason.

> "python3-modulemd-1.3.3-1.fc28.noarch requires python(abi) = 3.6"

This is okay.
But libmodulemd is currently calling pythonX-modulemd without obsolute?
I still do not know why pythonX-modulemd is called.
Comment 3 Miro Hrončok 2018-07-23 10:30:22 UTC 
pythonX-modulemd is not called, you just happen to have it installed and it can only go away with explicit removal or being obsoleted or if you use --allowerasing.
Comment 4 Stephen Gallagher 2018-07-23 14:42:50 UTC 
I added `Obsoletes: python-modulemd` to libmodulemd and built it today. This should be resolved when the next Rawhide compose finishes.

The reason it was reverted previously was because dnf was still depending on python3-modulemd. That's no longer the case, so I re-added the Obsoletes.

Comment 7 Jun Aruga 2018-07-26 11:34:47 UTC 
I could install it with

```
# dnf --allowerasing install ...
```
