Cron change directory error preventing start

[pageb018]

Behaviour

Steps to reproduce this issue

1. Try starting the stack by running docker-compose up -d
2. Tail the logs and notice cron errors
3. Nextcloud will not start

Expected behaviour

Nextcloud should start as normal.

Actual behaviour

containers exit with various exit codes

Configuration

• Docker version (type docker --version) : 23.0.1
• Docker compose version if applicable (type docker-compose --version) : 2.16.0
• Platform (Debian 9, Ubuntu 18.04, ...) : Debian LXC
• System info (type uname -a) :
• Include all necessary configuration files : docker-compose, .env, nextcloud.env all copied direct from examples.

I should not that the stack had been running correctly for months without issue. This was new after a reboot.

Container logs (set LOG_LEVEL to debug if applicable)

I can't repro on my side. This folder is created on startup: https://github.com/crazy-max/docker-nextcloud/blob/5f70a17b702268d223560d577ab7f9d9cf94758d/rootfs/etc/cont-init.d/05-svc-cron.sh#L18 So not sure how it happens.

Would need repro to help if you still have this issue (compose file).
