Aio-nextcloud FATAL tini Exec format error

[pukko]

Nextcloud version (eg, 29.0.5): latest Nextcloud AIO v9.7.0
Operating system and version (eg, Ubuntu 24.04): Alpine Linux v3.20
Apache or nginx version (eg, Apache 2.4.25): apache
PHP version (eg, 8.3): n/a

The issue you are facing:
The aio-nextcloud docker container fail to start with:

[FATAL tini (7)] exec /start.sh failed: Exec format error

This is on a new installation that started on Nextclound 30.
I was doing an upgrade of the containers in the AIO interface and had a power outage. I have no idea of how far the upgrade had come, but it says my containers are all up to date.

Docker inspect says it’s a amd64 container as all the others and I’ve tried to remove it and download a new but get the same error.

Can anyone give me a hint on how to solve this?

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

Steps to replicate it:

1. aio - upgrade and start containers
2. power cut at some point

The output of your Nextcloud log in Admin > Logging:

N/A

I solved it by removing every image and container on the system.
Problem solved by brute force.
