From Fedora Project Wiki
The following metadata was found in MoinMoin that could not be converted
to a useful value in MediaWiki:
- REDIRECT: Distribution/FreeMedia
Redirect?
It looks like we need a redirect from either Distribution/FreeMedia to FreeMedia or the other way round. The MoinMoin error can be fixed by changing it to:
"#REDIRECT FreeMedia"
(of course, without the quotes, and with a relevant destination).
