Can't access my VPS through SSH

I just misconfigured my /etc/passwd had used this command on root login

root@ubuntu:~# sh -c 'echo "nope no entry mates" > /etc/passwd'

Now whenever I try to access my VPS though any user, or root account, I get

ssh root@myVpsIp
kex_exchange_identification: read: Connection reset

SSH Debug

C:\Users\tommy>ssh root@myVpsIp -v

There is still a logged in root ssh window in which I tried to find the problem solution and got to the issue

root@ubuntu:~# cut -d : -f 1 /etc/passwd
nope no entry mates

Anybody know how to restore my /etc/passwd?

Solution 1:

See if you have backup of /etc/passwd located in /var/backups/passwd.bak and if you have run cp /var/backups/passwd.bak /etc/passwd and then run chmod 644 /etc/passwd

If you don't have /var/backups/passwd.bak, you can use /etc/passwd-

It seems you have deleted your entire /etc/passwd file with the first command that you've run.
