If your device is built from an image created from your own Custom model assertion, then you should already have access to these values. access to the key used to sign the new assertionĬreating a valid system user assertion is limited by the model assertion which contains store account ID defined as brand-id and authority-id, alongside the model name, model.the brand-id and model fields taken from a device’s model assertion.

If you want to give them sudo privileges, also run. For instance the following will create a user home directory in the typical place: Code: sudo useradd -m username. This creates the file containing the assertions for account, account-key and the new system user automatically, and requires only the following: You can use any existing account or add a new Samba only account with the following command. useradd might be a better option than adduser. While auto-import.assert can be created manually, it’s far easier to use the make-system-user snap. After this, you can log into the device (locally or over SSH) using the username and password defined. If those assertions are valid for the given system, a system user is created. If you want to create a new user and add into a group by using just single command, use the ‘useradd’ command to add a new user and then add this user into the primary and secondary group by using the following syntax: sudo useradd -g group -G group1,group2 username. The snap daemon can import account, account-key and the new system user as a stream of assertions in auto-import.assert from an external USB storage device. Create a New User and Add in Multiple Groups in Ubuntu. A system user cannot typically be added to a system that is already managed. By default, Ubuntu Core images run a program called console-conf when they’re first instantiated on a device.Ī managed system already has a user account whereas an unmanaged system does not.
