Found the issue for some reason Nextcloud was not able to connect to APC anymore changed the Variable to APCu and now it works.

[sbrl]

On updating from 17.0.1 to 17.0.2, I encountered this issue. I do not have APC or APCu installed but had this auto-added to my config file:

memcache.local' => '\\OC\\Memcache\\APCu',

.....commenting it out fixed the issue.

You wouldn't expect a point release to cause such a serious issue (I got a nasty white screen with a plain text message), but apparently it did.

[kesselb]

Would you mind to report a new issue https://github.com/nextcloud/server/issues/new?labels=bug%2C+0.+Needs+triage&template=Bug_report.md?

I'm not aware of any code that changes memcache.local during updates. To triage this properly we need the issue template (server setup, including logs, installed apps, etc.).

We usually don't reopen issues for such old versions. A new issue with up to date information is clearer. Thanks in advance 👍

[sbrl]

Erm can do, @kesselb! I've fixed the issue now by following the step above though, so I'm not sure how much use it would be?

[juchong]

I also ran into this same issue. I'm happy to chime in on the eventual new issue if someone can point me to it.

[sbrl]

I could never reproduce the issue again @juchong, so I'd advise opening a new issue yourself since I'm not in a position to open a new issue anymore.

I see this in the error log:

What should I do?

[Sonnenbrand]

Same here

[juchong]

Hi folks,
I'm assuming that everyone here is using the Nextcloud Docker container? My issue went away after I pulled the latest image. Maybe something was pushed to main that was broken?

Thanks for the advise, tried that but still no change!

[sirojinadias]

Same here, updating to PHP7.4 fixed it.

[satarsa]

I've got this error message after redis segfaulted, if it may help to track it.

[MrTomRod]

For me, the problem was that I somehow autoremoved php7.4-apcu.

Had to reinstall it: apt-get install php7.4-apcu

This was totally related to redis not properly starting after 22.04 upgrade for me.

Fixing upgrade changes made in redis.conf and restarting fixed this for me.

I also updated ubuntu 22.04 and got the same error, I am using it with Redis disabled.
If you don't mind, could you please tell me the contents of your Redis configuration file?

To clarify, my redis was starting, but attaching to a tcp port instead of a local unix socket :)

I'm running the stock 22.04 redis config, with these two changes;

• port 0
• unixsocket /var/run/redis/redis-server.sock

They were overwritten during the upgrade to 22.04 when I chose 'Y' to replace current config with package maintainer's config version.

I rebooted entire system after change, and nextcloud was back up and normal afterwards. But just restarting apache2 and redis services should be sufficient to bring it back up after correcting those redis settings.
