Hi Konstantin, Thats good news.
Now you need to update the host identification for E31x, as it's fingerprint has changed. Within the Linux VM, remove the file /home/user/.ssh/known_hosts with the commnad: rm -v ~/.ssh/known_hosts Then attempt to login again, you'll be prompted to verify the fingerprint, type "yes"., and you should then be logged into the E3xx.
