Tips for increasing the likelihood of a response

Use the preformatted text formatting option in the editor for all log entries and configuration output.
If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.

Do by chance have multiple config files in config/, such as a backup from when your instance was running v32.0.0? Nextcloud loads all *.config.php files located in that folder and merges them.

GaryYoung · December 22, 2025, 3:10am

Hi JTR - thanks for the reply.

There was a config.sav file (now moved out) but running sudu -u apache php /var/www/html/nextcloud/updater/updater.phar still produces:

Nextcloud Updater - version: v32.0.2-1-g59d8255 dirty

Current version is 32.0.3.

No update available.

Nothing to do.

SysKeeper · December 22, 2025, 5:57am

32.0.3 is the latest version?

GaryYoung · December 22, 2025, 6:55am

Yes I am aware of that, but the “auto update” via Nextcloud Updater keeps trying to downgrade…..

SysKeeper · December 22, 2025, 6:59am

But from the posted output it looks now alright ?

GaryYoung · December 22, 2025, 7:38am

No - every night for an hour (every minute) the same error appears in the email from Cron.

TurabG · December 26, 2025, 10:23am

I have this problem too. The instance is completely broken now.

My normal upgrade process is this:

Run php updater.phar
After the successful upgrade, replace the docker image with the corresponding version

I have been using/upgrading Nextcloud this way for years now. Today I ran the upgrade process and it successfully upgraded to version 32.0.3. Then I deployed the image with tag 32.0.3, but it won’t start, giving the same error in the first post. It complains that the actual version is 32.0.3.2 but the image is 32.0.3 which is why it sees that as a downgrade.

jtr · December 26, 2025, 8:37pm

What do you mean by the “auto update”? Nextcloud Server does not have an automatic update mechanism (other than the one in AIO).

No - every night for an hour (every minute) the same error appears in the email from Cron.

What does this nightly cronjob contain?

HintException Downgrading is not supported and is likely to cause unpredictable issues (from 32.0.3.2 to 32.0.0.13)

The latter comes directly from the version.php of the installed code in your installation directory.

jtr · December 26, 2025, 8:38pm

Your situation is likely different since most of the Docker images have different update/upgrade mechanism. Though the approach you’re describing sounds very strange for the images I’m aware of. What image are you using? And please share your Compose file.

TurabG · December 27, 2025, 8:47am

I am using the official Docker image. (docker pull nextcloud:32.0.3) I am deploying it on Caprover, which first deployed it on its own config here:

TurabG · December 29, 2025, 7:48am

Solution for me: This was because I overrode the php config dir; which needed updating with version 32.0.3. So I deleted the volume, restarted the container, now everything works back. (The reason I overrode the php config dir was because the default memory limit was insufficient.)
