Trouble using Sangoma 6 to 7 upgrade tool

I attempted to look at my resolv.conf file to check DNS entries like tim007 did, but I can’t get a command line. I’m stuck at this screen below. I’ve tried ctrl+c and several other potential keys to get a command line. I even ran my hands over the keyboard in frustration, but can’t get a command line. Is there a trick to get a command line?
