I am trying to mirror two repositories from OpenHPC.They are: - [http://repos.openhpc.community/OpenHPC/3/Leap\_15/](http://repos.openhpc.community/OpenHPC/3/Leap_15/) - [http://repos.openhpc.community/OpenHPC/3/updates/Leap\_15/](http://repos.openhpc.community/OpenHPC/3/updates/Leap_15/) There is an rpm file that adds them directly to a client (not using RMT) and that works correctly and both repositories are added and enabled. However, with RMT I can only mirror the first one. The updates repository is added correctly but when I try to mirror it I get the following: ```auto desdemona:/var/lib/rmt/.gnupg # rmt-cli mirror repository openhpc-updates I, [2026-04-24T14:50:47.429204 #24599] INFO -- : Mirroring repository OpenHPC Updates to /usr/share/rmt/public/repo/OpenHPC/3/updates/Leap_15/ I, [2026-04-24T14:50:47.715967 #24599] INFO -- : ↓ repomd.xml I, [2026-04-24T14:50:48.002201 #24599] INFO -- : ↓ repomd.xml.key I, [2026-04-24T14:50:48.003645 #24599] INFO -- : ↓ repomd.xml.asc W, [2026-04-24T14:50:48.031919 #24599] WARN -- : GPG command: gpg --homedir /tmp/rmt-mirror-gpg20260424-24599-10ybaiv --no-default-keyring --keyring /tmp/rmt-mirror-gpg20260424-24599-10ybaiv/keyring --verify /usr/share/rmt/public/repo/OpenHPC/3/updates/Leap_15/.tmp_metadata/repodata/repomd.xml.asc /usr/share/rmt/public/repo/OpenHPC/3/updates/Leap_15/.tmp_metadata/repodata/repomd.xml 2>&1 W, [2026-04-24T14:50:48.032013 #24599] WARN -- : GPG output: gpg: Signature made Thu 30 Oct 2025 14:01:51 GMT gpg: using RSA key 5392744D3C543ED5784765E68A306019DA565C6C gpg: Can't check signature: No public key W, [2026-04-24T14:50:48.033814 #24599] WARN -- : The following errors occurred while mirroring: W, [2026-04-24T14:50:48.033855 #24599] WARN -- : Repository 'OpenHPC Updates' (openhpc-updates): Error while mirroring repository: Error while mirroring metadata: GPG signature verification failed.

Can anyone advise? Thanks ---

> gpg: using RSA key 5392744D3C543ED5784765E68A306019DA565C6C > gpg: Can’t check signature: No public key I don’t think the issue is from rmt side. You can reproduce the issue by doing similar gpg command. I think the 2nd repo is not signed correctly. The fingerprint for [https://repos.openhpc.community/OpenHPC/3/updates/Leap\_15/repodata/repomd.xml.key](https://repos.openhpc.community/OpenHPC/3/updates/Leap_15/repodata/repomd.xml.key) is ```auto pub rsa2048 2023-04-19 [SC] [expires: 2045-03-14] 6E19BE11D9A082C00A7DB41A7AC05F0940A90CC8 uid OpenHPC3 OBS Project ``` Not like the working one: [https://repos.openhpc.community/OpenHPC/3/Leap\_15/repodata/repomd.xml.key](https://repos.openhpc.community/OpenHPC/3/Leap_15/repodata/repomd.xml.key) ```auto pub rsa2048 2019-12-16 [SCEA] 5392744D3C543ED5784765E68A306019DA565C6C uid private OBS (key without passphrase) sub elg2048 2019-12-16 [E] ``` You need to reach out to them so they include the correct key in the URL. ---

I have reached out to them and am awaiting a reply. If I have no success with them, is there a way to disable the requirement for signing that repository? ---

I don’t think this is possible. Let us know the result. ---

I will. Out of curiosity, are different criteria required when a repository is added directly to a SLES client rather than mirroring via rmt? The reason that I ask is that BOTH repositories can be added to a SLES machine via YaST. ---

YaST and zypper will ask you for confirmation, wheil RMT does it all automatically. If verification fail, it stop. ---

OpenHPC have provided the correct GPG key and mirroring now works correctly. Thanks for your help. ---
