Hi
Installation media usually means the install medium dvd or USB device, is there and active repository pointing to the install medium, eg;
```auto
1 | SLES12-SP1-12.1-0 | SLES12-SP1-12.1-0 | No | ---- | No | 101 | yast2 | hd:///?device=/dev/disk/by-id/scsi-20001020000060804-part2
```
If it is disable this repository and try a refresh.
Else is the system registered and have an active subscription to receive updates? Check via your SCC account at [https://scc.suse.com/](https://scc.suse.com/)

Hi Pasaputte,

is that the actual output (cut&paste), or have you manually typed the link? Because not only the mixed case, but also the host name is really obscure.
In case you have actually registered your system via YaST or CLI, the proper URL should have been added automatically. Please check the following from the commend line, as user “root”:
- does “zypper lr -u” show the repositories and use proper URIs (you may show the complete output here if you want us to verify)
- do you need to use a proxy to access the Internet? Are the environment variables set accordingly? (“env|grep proxy” should list corresponding entries for at least “https\_proxy” and/or “http\_proxy”)
- does running the update via that command line (where you verified the proxy settings) work?
Regards,
Jens
