Nextcloud installation fails

Apps and Virtualization
1

Hello,

I can’t seem to get the Nextcloud installation working on Nextcloud Scale 25.04.1
The installation fails and points to /var/log/app_lifecycle.log where the following errors are logged.

It’s worth mentioning that I can install Nextcloud to the default iX location but not to a host path, even though I have created a dataset for the dataset and given the user and group www-data ownership and full permissions.

Any help is deeply appreciated!

if your dataset is nested into another dataset (example, like i have, POOL/DOCKER/NEXTCLOUD/…), is mandatory that the user/group involved can traverse into the dataset on top, otherwhise you will ever end with access denied error (taking my example, the DOCKER dataset)

Hi oxyde, I appreciate your answer.

I still can’t get it to work. Posting below the output of getfacl and ls -ld up to /ncdb which is the selected dataset for the database to be installed.

i think the problem is just this

the owner-group should be netdata (the user with the gid 999); www-data must be the user/group of the other dataset, the one with the data.
Hope this helps

Thanks Oxyde!
This worked (quoting from here Cannot install Nextcloud App from listing ONLY when using non-IX paths)

After a lot of trial an error today, I was able to get it working (fresh install) by using the CLI to create my directories and assign the following users and permissions:

  • App Data: 755 www-data:www-data
  • User Data: 755 www-data:www-data
  • Postgres: 700 netdata:docker
