Description

This update has some flaw with the upgrade where rsync is hung indefinitely. Exec into the pod and only these processes are running:

root@nextcloud-server-5f8cb45955-ss5rk:/var/www/html# ps aux
USER         PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

This was left like this for a couple hours and never finished. It appears the rsync commands just hang and never return or exit.
image being used is: 25.0.3-apache

Not sure what was broke in this new version (I have successfully upgraded in the past), but rolling back to 25.0.2 and it's working again.

Research direction

Inspect the 25.0.3-apache image and /entrypoint.sh, focusing on the rsync commands shown in the report. Reproduce the upgrade while comparing 25.0.2 with 25.0.3; done means the upgrade completes and does not leave rsync processes stuck indefinitely.
