Hi SUSE Community,
New to the big family here, recently was tasked to upgrade the existing virtualization server of SLES 12 SP4 to SLES 15. But was met with an error after the, “Previously Used Repositories” page. The error is as follows, "Internal error: Failed to open TCP connection to scc.suse.com:443 (getaddrinfo:Name or service not known). I tried searching for some hints on the net but couldn’t find anything useful. I hope the fam here could help me out.
*I have internet connection to the virtual machine on SLES 12 SP4 before running the update package:SLE-15-Installer-DVD-x86_64-GM-DVD1.iso
