Upgrade OC 8.1.1 to 9.1

[quote=“CliffMitchell, post:11, topic:1333”]
How can I get back to having the correct update notifications on the Admin page with the option to manage updates from there?[/quote]

Seems 9.0.4 is not provided in the “stable” update channel yet:

https://updates.owncloud.com/server/?version=8x2x7x7x1382907615.86x1435439812xstablexx2015-02-07T02:34:55+00:00

but only in the “beta” channel:
