openSUSE Leap Micro was the last to the party to receive the extended openSUSE signing key following its recent expiration. We’re deeply sorry for the inconvenience. The underlying issue has now been resolved everywhere.

If your system still encounters repository signature errors, you can refresh the repository metadata and fetch the updated signing key manually.

The zypper ref -f command forces a refresh of the repository metadata, including the new GPG signing key. Normally this should happen automatically, but the current version of libzypp may not always retrieve the updated key correctly. Forcing a refresh resolves the problem. Just to note that the zypper ref -f will force new key on any openSUSE distribution.

Run the following commands:

transactional-update shell zypper ref -f zypper dup exit # from tu shell 

After rebooting into the new snapshot, your system should be using the updated signing key and repository refreshes should work normally again.

Have a lot of fun!

Koguma is a renovated old house cafe that was originally a pharmacy built in 1927. The shelves inside the shop are medicine cabinets that were used in the past. Other items such as medicine drawers, a grandfather clock, and a sewing machine have all been kept in the house for a long time.
