Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can :heart:

Nextcloud version (eg, 17.0.9 - 18.0.9):
Operating system and version (eg, Ubuntu 20.04): Ubuntu 18.04.5
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.29
PHP version (eg, 7.1): 7.2.24

The issue you are facing: I upgraded from 17.0.2 to 17.0.9 in the browser updater without issue. Then, in Settings>Overview, it showed another update, to 18.0.9, so I clicked that. It did the download bit and then returned me to Nextcloud to complete the upgrade and then gave me a warning that the apps would be upgraded and some would be disabled because they were incompatible.
It started upgrading apps and then suddenly switched to maintenance mode. It’s been in that state for twenty minutes or so and I am getting very nervous. Am I right to be?

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. I can’t, because it’s frozen.

I’m guessing this is what’s needed: it’s the error log from the Apache2 folder in /var/log/
I’m leaving it on and going out for a while, to unwind. :confounded:

Any help or reassurance much appreciated.

Hi.

I’ve run into an issue like this before. Here’s what I did to resolve it.

don’t forget, if it’s a VM, take a snapshot before you do anything major so you can recover.

Thank you, copenhaus. The link showed me how to turn off maintenance and the upgrade then went ahead.
I’m back, with a lovely, shiny, far more up to date Nextcloud. Thanks again.

Edited because I’d said something stupid. I’ve been doing some more research and understand my error.
