What Happened?
The Fienix software repository was "unreconciled" due to an unexpected interruption to an update process. Unfortunately, a backup did not exist. Effort to reconcile the repository were unsuccessful. This caused package unavailability, broken packages and broken updates.
What Now?
The Fienix software repository has been taken offline. Repairing the repository for the current 6.x version is not feasible. I hope to restore it for a 7.0 release. This would likely be several months away.
What Should You Do?
If you have installed all the packages you want/need, you don't need to do anything. Browser updates are generally posted to the "Linux on PowerPC" Facebook group, Hyperion forums, and elsewhere. You can also get packages from Debian, or switch over to Debian completely.
