This notice from zypper came up several days ago and I was hoping it was just a repository error, but it hasn't gone away. It's actually preventing me from performing the distribution upgrade.

Code:
linux-q5o0:~ # zypper dup -l --no-allow-vendor-change
Warning: You are about to do a distribution upgrade with all enabled repositories. Make sure these repositories are compatible before you continue. See 'man zypper' for more information about this command.

  http://packman.links2linux.de  -->  openSUSE

Do I need to remove that package and then reinstall again from Packman? As I understand it, I don't want to change vendors Packman --> openSUSE, correct?
