Comment 3 for bug 1814586

I have checked about 1004 and got:

    ls -ld /
    drwxrwxr-x 32 1004 1004 4096 Dec 9 23:22 /

- it is really strange.

So I ran

    sudo chown root: /
    ls -ld /
    drwxrwxr-x 32 root root 4096 Dec 9 23:22 /

And reinstalled SSHD again:

    sudo apt-get install --reinstall openssh-server

without errors:

$ systemctl status sshd.service
