I add the SDK ISO file repository of SLES, but execute "zypper in" command, it outputs:

# zypper in gdb
File '/media.1/media' not found on medium 'http://xxxx.net/mrepo/SLE-12-SP1-Server-RC2-x86_64/disc2/'

After checking the repository, there is indeed media.2 folder, no media.1 folder.

So how can I add SDK ISO file repository successfully? Thanks very much in advance!
