Expiring gpg key opensuse

1. Use the existing docker image with osc tool installed. If you want, you can install it locally and follow these steps.

   docker run --name=osc --rm -it rtcamp/nginx-build bash
   docker exec -it osc bash
   

2. Extend the expiry date for the key,

   osc signkey --extend home:rtCamp
   

3. Get the updated key,

   osc signkey home:rtCamp > public.key
   

4. Upload to a keyserver,

   gpg --import public.key
   gpg --keyserver keyserver.ubuntu.com --send-key '3050AC3CD2AE6F03'
