Hi, I’ve download and successfully boot the ubuntu server image. 2 problem that I encounter at the moment

  1. when trying to ssh from the F2P board, I always get Connection close by xxx.xxx.xxx.xxx port 22
  2. when trying to do apt upgrade - I have error at initramfs - undefined /dev/root

please advise

Thank you
