@cesarizu your solution worked for adding the repository. Thanks a lot!
I got Insync running now, but the setup is kind of “dirty”. I needed to install “insync-nautilus-opensuse” and hit CTRL+C while installing insync to get the setup “complete”. It seems, that there is a problem with a Python script right in the end of the insync setup routine. See my log:
$ zypper -vv install insync-nautilus-opensuse

But anyway, thank you for your help, I can use insync now again! =)
