Have you created such a group? It isn't there by default. 'adm' I have, but
not admin.

Well, if your /etc/sudoers file is in its original state, the group 'adm'
isn't mentioned there. Thus I think adding a user to said group wouldn't
give this user sudoer rights. Plus I wonder how that group came there in the
first place.

Check if you can boot into single-user mode, and work your default or the
other user into /etc/sudoers. The syntax as created by default is:

# User privilege specification
<username>   ALL=(ALL) ALL

Hope this sorts it out.
