Server closing connection after ssh login

Working on archlinux, last updated today. Tried to setup a web application on the server. Got error 'core dumped' when tried su, decided to reboot. After reboot the problem started.

ssh -vvv output after I input my password(can provide full log if needed):

Tried to play with -t param.

ls outputs go, cat /etc/passwd file not found, cd and a lot of other commands: command not found

Have no idea what happened, as well as what to do.

Also, I have physical acess to the machine, but would like to stay in ssh(it's kinda difficult).

The answer is very stupid.

I've tried a lot of different solutions to fix this, but the answer was quickly press ctrl+c after login. Then, I could do my stuff.

I remember like I tried to install some yum packages, or something like that, and after a week noticed the problem(didn't checked server after reboot). Maybe update freezed the system?. Not sure.
