I have used the Yast CA modules, years back. And now, it’s time to update the CA’s certificate as it expires an a few days. Since the Yast2 CA module is not part of the Leap 15.1, I have to do it manually.
So, the question is where did the Yast2 module save the private keys and the CSR?
Without researching this,
The following thread recommended xca.
You might try installing on the long shot chance it might find your old certs automatically (if they’re located in some standard location).
CA root should be /var/lib/CAM.
