Title:
  Problem when upgrading to 26.04 beta after exiting a text viewer

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  This issue when upgrading to 26.04 beta, I had the bad idea to look at a Config file (or differences file ?) when asked, then I could not exit the text editor, then did a CTRL+C (perhaps the right command should have been ':q'), this broke the upgrade :(
  I was stuck on Ubuntu failing to load for several days, until I have the idea the select the previous Kernel version at boot. Still have no idea how I will fix the issue, I hope system updates will do it.

  Perhaps my report will help next users: Canonical please tell newbies
  how to exit this text editor before to open it :)
