I recently downloaded Ubuntu core from the official Ubuntu site (26/01/20) as I am trying to install Ubuntu core on my Raspberry Pi 3+ for my first time ever. I have setup an Ubuntu account and transferred my SSH key into it as requested. Unfortunately after copying the img to my SD card and booting my Pi, during the configure stage I am unable to generate a '@' key stroke for entering my email address. However all the aplhanumeric keys, the enter key, tab key, '-', '=', and '.' keys provide an output into the Email address box. I have tried multiple keyboards in multiple USB slots on the Pi. I was wondering is there a specific type of keyboard I should be using or not, or is there issue during installation with recognising specific keyboard?
Many thanks for any assistance you can give me
