Upgrade Nextcloud to ver 12.0.1 on QNAP

I use just change from OwnCloud to NextCloud on my QNAP TS453A (4 core Intel, 8 GB RAM).
Actually I use QTS ver 4.3.3.0262 build 20170727 (the lates avaliable).
I add community repo store.qnapclub.eu/store/pl.xml.
Using this repo I install NC ver 12.0.0. Now NC informs me that new version of NC is available. So I try to upgrade it using admin option “Upgrade”. Then it display info “Initialising” and I waited 1 hour but nothing happens.
NC on my QNAP works on Qapache ver 2.4.27.718, taken from the same community repo. So that is separated HTTP server with own PHP.
So how can I upgrade from GUI NC to the newest version?

The output of your Nextcloud log in Admin > Logging: (part of because forum limitation)

Why do you use the owncloud-app-store?

Do you use your cloud a lot? From a performance point of view, sqlite is very slow especially without an extra filelocking-cache.

I don’t see any errors related to the failed upgrade.

Ups. As I wrote, I just migrate from OwnCloud ver 8 to Nextcloud and this is a remnant of former config.php file from OwnCloud. So my I ask about proper URL?

The NC system is basically used only by two desktop PC. To share/sync documents between me and my Wife. Sometimes we access it from mobile platforms. We keep only documents of our 2 person company so amount of data is opprox 3,5 GB. So SQL Lite is enough.

I dont see any errors of failet upgrade but upgrade does not want to start.

Just remove the entry and it will fall back to the default url.

Did you skip major versions during your upgrade?

Manual upgrades should always work. A failure in initializing indicates that there is probably something missing or some very basic things don’t work (perhaps outgoing connections are not allowed).

The added complexity of it being a qnap community thing might be to blame

No. Ver 12.0.0 was the first NC instance I ever install on QNAP. It was not necessary to use any special procedure of migration from OwnCloud to NextCloud because my installation is rather small (2 active users + admin and 3,5 GB of data). So I simply started from fresh, empty database, sync it with my desktop and then with my Wife desktop. Installation was done from QNAP community repo, added to App Center.
So i try to upgrade manually.

There is 12.0.1 QPKG package dedicated for 64 bit Intel based NAS (just like my one). Can I simply install it over existing 12.0.0 version and it replace me older version with new one?

Nextcloud didn’t build these and we are no experts for QNAP apps. So better ask in a dedicated forum.

Ok. THX. We can close the topik.
