I have a bitnami owncloud image running version 184.108.40.206. When trying to upgrade to 9.1, the Update app only shows the 9.0.4 version and not the 9.1 version?
Yes, this is the expected behavior since ages. Major releases are mostly only available at the first or second point release (e.g. 9.1.1 or 9.1.2) via the web updater.
However you might want to change the channel to "beta" which is providing 9.1.0. But for now i HIGHLY recommend to wait for the 9.1.1 release which should be released within the next 1-2 weeks.
I have problem, that PVince81 said will be fixed in 9.0.5 (According to https://github.com/owncloud/core/issues/24575#issuecomment-240079542).
I was reading the thread https://github.com/owncloud/core/issues/25633#issuecomment-249718189 which highlights the release stages and the schedule page. According to the link, the current version is 9.0.5 in the 9.0 (stable) series and 9.1.1 in the 9.1 (fresh) series.
Is the another table that the update app uses, to get the latest stable release?
I just updated from 220.127.116.11 to 9.0.4 (on bitnami) and realized I needed 9.0.5. Will the update app show 9.0.5 to be stable soon, or will I need to wait till the end of the year?
Locking here as the question of the OP is answered and everything else should go into a new thread.
