There we go. You obviously changed the ownership and permission of the
wrong files and dirs.

/home/kelly still belongs to the user 'kelly' and his (private) group
'kelly'. That's fine. However, the permissions and ownership of /home is
totally borked...

/home should not belong to any particular user. As mentioned in my "sane
example" user and group 'root' would be sane.

/home needs some permissions for the users who do have their $HOME
there. Otherwise they will not be able to change to their own $HOME.
(Think of it as a door in front of your house. If you do not have the
key for that door, how are you supposed to enter your place?)

You need read and execute permissions to the world (others) for home.
Like my example below clearly shows.

(Besides, your output is from 'ls -la'... ;)

Yeah. You would not need root privileges, if the permissions of /home
where sane...

Should be fine.

I did not mention "rw permissions".

A file (same for dirs, which actually are files as well) has an owner
and a group assigned. You can set permissions for the owning user, the
group and anyone else -- often referred to as "world" or "other". That's
what I mean.

The owner of /home should be root, the group too. Permissions to other
applies to anyone who is not 'root' nor member of the group 'root'.
Which clearly applies to any user (unless someone changes it for a good
reason). "Any user" includes 'kelly'.

So you need to change the ownership of /home and grant proper
permissions to anyone else:

# chown root:root /home
# chmod 755 /home

Yup, we had that above already. It's the "." dir in your output above.

That's fine, if the files are actually owned by 'kelly'.

Please, read about these topics and the commands mentioned. Do
understand what the commands are about to do. Do not blindly try to use
them. It failed before...
