The 15.2 system needs to have latest zypper which fetches gpgkeys from repodata. Otherwise user has to specify --alow-vendor change to allow exchange of openSUSE signed rpms to SUSE signed and vice versa. I would also recommend to provide zypper logs and output from the dup without that we are only guessing. -- You are receiving this mail because: You are on the CC list for the bug.
