Comment # 15 on bug 1194660 from Ladislav Slez���k

Hm, it works fine for me on an x86_64...

You might try running this to get more details about the failure:

  curl -vvv
https://download.opensuse.org/YaST/Repos/openSUSE_Leap_15.3_Servers.xml" 


Also check that the CA certificates package is present in the inst-sys:

  grep certificate /.packages*

It should list the "ca-certificates-mozilla" package.
