well, i just checked after upgrading to 3.6.11-2 and the repository in question has now *entirely disappeared* from the config!
i've had to downgrade to 3.6.6-1 to get things functional (it's a live-running server) this does actually work, so during scheduled downtime moments i can switch to the broken version (3.6.11-2) and find out what the heck is going on. l.
