I used the command:

chown -R root /opt/xibo/shared/db to change the owner of db to root but the error still persists

Can anyone shed some light on this? The permissions look to be there?

Thanks

It looks like you’ve installed Docker from the snap store rather than from the Docker repositories.

You need to uninstall the Docker snap and install it using the guide we provide directly from the Docker repository.

Thanks, removed docker and reinstalled using the following guides:


When I copy my db into the shared folder I get an error about cms@ip address not allowed access but this was a test install migrating from a windows server install.

Thanks again.

You can’t just copy in an existing database.

If you want migrate from a custom install to Docker, then you need to follow the guide here:
https://xibo.org.uk/docs/setup/upgrade-and-switch-to-xibo-for-docker-install

You’ll need to down your containers and delete shared/db before starting.

I may of not been clear, i had switched to docker and had users and templates setup. The database i’m trying to copy back was from a working docker install, i started having issues when updating to the latest build.

You should still import the database from a mysqldump backup rather than copying in the raw database files.

Copying them in may work if the containers were all stopped/down when you took that backup, but if they were running then it won’t be consistent and you may well encounter issues. You’re always best taking a consistent mysqldump backup - or using one of the ones provided for you.
