Me and another tester ran into the same issue when testing the upgrade to NC20.0.5.
Many apps were disabled and had to be force-enabled and others completely disappeared from the app store, such as TOTP and News.
@DavideAccogli are you using NCP or plain NC on your Raspberry Pi?
I’m trying to make a list of the apps with problems
This is what I found after upgrade to 20.0.5. Can be more. At this moment is not easy to replicate all the instalation This is on Nextcloudpi Debian 10 x86_64 (curl instalation) and Nextcloudpi on raspberrypi 4 (nextcloudpi image).
There are no differences betwin the two.
In 20.0.4 all apps are working as expected.
Marked as untested and disabled by the upgrade:
Checksum
Deck
Metadata
Two-Factor Admin Support
Unsplash
Apps that disappeared from the app store/my installation:
Collaborative tags
Comments
Mail
News
TOTP
Two-Factor U2F
Bello, I’m using NC on Raspberry PI 4.
I downloaded version 18 at https://download.nextcloud.com/server/releases and upgraded stabile releases as they were available.
Thanks
So I’m not mad. TOTP disappeared.
I manager to install it manually and it works, but that it’s not the way it should be.
Please read this. Perhaps it is a solution for you.
Whi don’t you try the last Nextcloudpi image?
Is working well in version 20.0.4 and is optimized for raspberrypi.

Thanks, but my instance is in production and I prefer to maintan the main line.
Ok, you’re right.
I have an x86_64 in production and my old instance for testing (Raspberrypi 4)
I have another Raspberry PI 4 on which I can test, but I need at least to connect it to an USB disk.
Which image did you use?
thanks for confirming that you are NOT using NCP, but manually installed Nextcloud.
I was trying to determine if this is an issue of the NCP updater or a general NC update bug.
Lots of people use NCP in production, and there are many extras that are not present in vanilla NC. Of course it is a matter of preference, but nothing wrong with NCP in production.
On the contrary, stuff like auto backups and snapshots are very highly appreciated by users.
I’m sure there is nothing wrong with NCP, but I prefer avoiding installers and have full control of what I install. Just a matter of preference.
sure, just want to write that so other people don’t think there’s something wrong with NCP in production 
The image is: NextCloudPi_RPi_11-27-20 (Raspberrypi OS ARM64)
For testing you can use only the microsd card
I’m sure I’ll test it.
But the issue with vanilla Nextcloud remains.
yeah that’s the main point of this thread 
Thanks. This is a different issue, I don’t have that entry in config.php
And thats why Nextcloudpi is in V 20.0.4 at this time
yes, won’t push the autoupdate for everyone until we make sure it works
