Hello, Everyone I will do detailed troubleshooting on this later today, but I thought I'd see if you can figure this out with what I can remember...
I just did a fresh install of Fedora 23, with a brand new user account. I proceeded to copy certain changes to my PATH from my old ~/.bashrc (created on Fedora 20) Didn't copy the whole thing over, just copy and pasted what I really need right now. Then I log out and log back in. Or try to log back in... I get an error message that starts like this: "All shell packages missing" The login process hangs at this point. BUT, when I go back to the login screen, instead of "Sign in" or whatever it says, it says "Unlock" But, of course I cannot log in.
If I go back to the original .bashrc (as shipped with Fedora 23) and reboot, then I can log in.
Later on today, I will try adding just one alias, or one change to my PATH at a time, to see what it takes to trigger this. I'm sure I've made mistakes with my .bashrc & .bash_profile before, but I have NEVER had anything like this happen. And I've been using Red Hat/Fedora since Red Hat 7.0...
Thank you for your help.
