No module metadata when using yum proxy repositories
- What problem are you trying to solve?
I want to use Nexus Repository OSS to proxy Rocky yum repositories (for example Appstream) but Nexus doesn't create/support module metadata and there are issues when installing some packages. When executing dnf module list I get empty list. I'm looking for a way around this problem, I'm wondering if it's possible to somehow generate metadata manually or fix it in some other way.
One example is that when I'm using proxy repository I cannot install docker because module container-tools isn't visble for packet manager.
- Do you have a workaround you are using at present?
No, I am looking for one.
- What feature or behavior is this required for?
To install some packages which use modules feature from RHEL.
- How could we solve this issue? (Not knowing is okay!)
I think the problem is that Nexus does not generate a file module.yaml.gz in repodata? I'm not sure but that is my guess.
- Tell us about your Nexus Repository deployment: what version, operating system, and database are you using?
Nexus Repository OSS 3.53.1-02 on Rocky Linux 9.2
Thanks @yeradd12 for opening an issue. We aren't familiar with Rocky linux, so this is a new area for us. We'll keep this open to gauge demand and interest from the community.
I experience the same problem with almalinux
I think this problem affects all derivatives of Red Hat 8+ as all of them use module functionality.

Do you plan add support for RHEL 8+ and when? CentOS is reaching eol and many companies will switch to alternatives.
Same issue. Since Nexus3 changed how files are stored it's trickier to create a script as workaround. @nblair https://github.com/rpm-software-management/modulemd-tools this is the tool I have used to create the metadata previously.
Same use for me on RHEL8 and Oracle Linux 8. I can't do "yum update" after installing some fonctionality like "cpan" that use module mode to download updates.
I have a same problem on rockylinux9 and almalinux9.
The error log is "Error: Failed to download metadata for repo 'baseos': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried" on rockylinux9 and almalinux9.
@nblair Do you have any plan to support centOS 8+ ? Can I know when will you support centOS 8+ ?
Sonotype support eventually clued me in.
They have no plans to generate this wacky metadata, but there is a raw repository type that just serves up the data as-is, like a regular static web site. For local snapshots of Linux package repositories, this does the job, and avoids the manifold shortcomings of a proxy repository / group.
Use repoclone to snag an upstream snapshot then nexus3-cli to recursively stuff it into Nexus.
