Had an issue recently with SUSE Linux where I saw this:
warning: /var/cache/zypper/RPMS/rpmname-9.3.0-6104.s12.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 7baa810c: NOKEY
Checking directory paths.
2019-11-16T10:29:00-05:00 Package installation failed
If you run into this, I would recommend:
- Run the command “zypper ref -s” to see if it would refresh the cache and service.
- Check if the quota exceeded on the server by reviewing the SUSE knowledge base article: https://www.suse.com/support/kb/doc/?id=7017376
