FC2 - root login not possible $HOME is not set

[mschievano]

Hello everybody, this is the error I get when try to SUDO root (or su root) in FC2.
It's not possible to login with root from kdm, and fortunately I have had the possibility to create an user (this from which i'm writing now)
Do you know how can i resolv? The problem happens after install deinstall something I can't remember.

Thanks

What happens if you Ctrl-Alt-F1 to a text console and try to login as root there?

I can login, but it show me the -sh-2.05b prompt, warning me that "no home found - logging with /"

Do a cat /etc/passwd and see what it says for root at the top!

Should be this:

root:x:0:0:root:/root:/bin/bash

[mschievano]

this the result:
root:x:0:0:root::
bin:x:1:1:bin:/bin:/sbin/nologin
daemon:x:2:2:daemon:/sbin:/sbin/nologin
.... etcetera

[AndyGreen]

Well, replace your broken top line

root:x:0:0:root::

with this

root:x:0:0:root:/root:/bin/bash

and your problem is over.

That's do the job. Thanks!
