As SUSE Linux 10.0 has reached its end of life in November last year, the Packman team will be removing all SUSE Linux 10.0 packages from its repository end of this week. If you want to keep them aside, make sure to download a copy before.
And as for good news, the Packman team has started to build its packages for openSUSE 11.0 (against Beta 1) since a few days. You can enable it by going to YaST -> Software Management. From there select Repositories -> Manage Repositories in the menu. Then select Add -> Community Repositories, and from here select the “Packman Repository”.
The codecs one-click-install for 11.0 should be updated and available next week.
