I am unable to sign in to Ubuntu Core 20 on a Raspberry Pi 2 because it won’t accept the ‘@’ sign when trying to enter the SSO details. I am also not able to enter any other special characters such as ‘$’. This is with a German keyboard, but typing the keys that would create a ‘@’ or ‘$’ on a UK keyboard also does not work.
Using Ubuntu Core is quite cumbersome compared to other embedded systems. It would help if there would be a headless setup mode, or even better, a mode that allows configuring with a configuration file placed in the filesystem.
