i did update my machine with pacman -Syu. after rebooting, i cannot login. i con see this error Failed to start Virtual Console Setup a tiny second right before log in screen. i had to capture it in slow mo to able to read it. i attach the image below.
and on the login, after i enter my username and hit enter it just hangs for a while without asking the password and asks for username again. it acts like when you enter wrong password.
Fix
turns out /bin some how got messed up. thanks to @wwwgem, i looked into system logs (journalctl) and fixed it
That warning comes up if you are using sd-vconsole but do not have systemd in the mkinitcpio hooks. You should fix that but it is most likely unrelated to the login issue.
Login issues normally hint at either the user shell or pam configs being wrong but you can also get this behavior if (the users home directory is on a secondary disk && that disk failed to mount && you aren't using systemd-homed).
sorry for late reply. yeah, my
/bingot messed up somehow, thats why it couldnt find the essentials, more likely bashCool, saw your logs just a while ago with the error about being unable to execute /bin/sh so I figured as much. What did you do to get there? I've never had an update fumble that hard...
I'm my experience usually you get assigned a home dir of "/" and a warning message if your home directory can't be found. But you can login.
