The message from yunohost on the screenshot worries me a little…
I am running nextcloud in a docker on an arm-device.
Can i install it without crashing nextcloud or loosing any data?
EDIT:
Just had a look in the docker-compose.yml of nextcloud:
The database- and the app-volumes (nextclouddb und nextcloudapp) are on my harddisk, so the only thing that could happen, is that mysql is not working anymore.
It is almost a fresh armbian. I just installed omv, docker, portainer and nextcloud (docker). Yes, my plan was to move to the nextcloud in yunohost, if i like it.
