I'm running Ubuntu for Windows, and I created a second user. I go into the users /etc directory to edit the passwd file so that I can use a custom shell on login, but there are some problems.
Running emacs passwd doesn't allow me to make changes for permission reasons.
So I try to the command sudo emacs passwd and it tells me that I'm not in the list of sudoers and that it will be reported.
Since I'm on ubuntu for windows, I don't think I can run the safe mode recovery fix, so I'm at a deadend.
Any help would be appreciated. Thanks!
I actually just realized a way to fix your problem.
Login to the primary user and sudo edit the file.
