We have been using Nexus to proxy OpenSUSE RPM repositories.

This has worked fine up until now, when we got an invalid repository.

```auto

```

How can this file just be gone from the repository?

I have tried everything to fix it:  
Invalidate cache  
Rebuild index  
Deleting RPMs  
Deleting repodata

But the repository is never being rebuilt.

I tried to create the task `Repair - Rebuild Yum repository metadata (repodata)`, but something in that is broken, because I cannot select a Yum repository. The drop down list for repository will not open up (or is empty).

**Edit** :  
The repodata eventually came back after I deleted it, but it does not contain any file other than repomd.xml and repomd.xml.asc. The repodata file is referring to files that are not there.

**Edit2** :  
I deleted the repository i Nexus, then recreated it.  
After Nexus has created repodata, there is now also one “_-deltainf.xml.gz" and one "_-primary.xml.gz”.  
However now, it fails with refresh. It complains about wrong file size

This file is actually 2.8MB showing in Nexus.  
The correct size is actually 567KB from OpenSUSE, so why is it 2.8MB in Nexus?

I don’t think we support the deltainfo file, at least I see no references to it in the code. Possibly this is something OpenSUSE has started using recently.

It must be very recently then. The Yum Proxy has worked fine up until now.  
Found an issue that seems related to this, but it is an old issue.
