Ubuntu 16.04 Immediately Logs Out When SSH Into Server

When I am trying to log into my Ubuntu 16.04 server via ssh I get immediately logged out after typing in the password. This is only for the justin user account. I am able to briefly see this message:

Could not chdir to home directory /home/justin: Permission denied
/bin/bash: Permission denied
Connection to localhost closed.

It appears that it is some kind of error message, but when I log in via Root (which successfully logs in) and run ls -la /home/justin I get the following output:

It appears as though every thing in the directory is correctly set to the justin permission group/user. I have also run sudo chown justin:justin /home/justin but I get the same results.

I have restarted the droplet to just to make sure. I am not exactly sure where else to look for information concerning this error. If I could be pointed to a log file that might have more information that would be helpful.

Thanks.

Hi @LordOfBytes,

most probably the file /bin/bash is with root:root ownership and 0644 permissions.

bash should be executable by everyone. To make it executable by every user on your system, you would need to change it’s permissions

chmod 755 /bin/bash
