Summary of the issue you are facing:
I’m trying to install for the first time using the AIO method, i tried both with docker run command and with the docker compose, i got the same errors.
Steps to replicate it (hint: details matter!):
-
Run
docker run --init --sig-proxy=false --name nextcloud-aio-mastercontainer --publish 8081:8080 --volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config --volume /var/run/docker.sock:/var/run/docker.sock:ro ``ghcr.io/nextcloud-releases/all-in-one:latest -
The container does not start and the only output is:
