Wie Du anhand meiner Angaben in der Ursprungsmail siehst, ist der inhalt
der authorized_keys sowohl für "user" als auch für "root" auf beiden
Systemen wie auch zwischen den Accounts identisch. Als "user" kann ich
mich bei beiden per Keyfile einloggen, als root nur auf einem.
Ich zitiere nochmal:
root@stretch64vm:~# md5sum /home/user/.ssh/authorized_keys
de1021845a76ef36c285d2b10e58e522 /home/user/.ssh/authorized_keys
root@stretch64vm:~# md5sum /root/.ssh/authorized_keys
de1021845a76ef36c285d2b10e58e522 /root/.ssh/authorized_keys
root@stretch:~# md5sum /home/user/.ssh/authorized_keys
de1021845a76ef36c285d2b10e58e522 /home/user/.ssh/authorized_keys
root@stretch:~# md5sum /root/.ssh/authorized_keys
de1021845a76ef36c285d2b10e58e522 /root/.ssh/authorized_keys
> ssh-copy-id kennst Du auch?
Ja, so kam der Key auf den jeweiligen "user"-Account.
Dort dann su -, anschließend kopieren von /home/user/.ssh/* nach
/root/.ssh/ und Kontrollieren/Anpassen der Rechte und Besitzverhältnisse
von .ssh und .ssh/authorized_keys.
Ebenfalls nochmal zitiert, aber diesmal pro Verzeichnis die beiden
Server gegenübergestellt:
root@stretch64vm:~# ls -lahd /root/.ssh/
drwx------ 2 root root 4,0K Jan 5 17:46 /root/.ssh/

Ist es aber. Die Config mag woanders entstanden sein, funktioniert ja
aber auf dem einen der beiden Systeme genau so, wie sie soll.

Funktionierende Maschine:
root@stretch64vm:~$ dpkg-query -l '*ssh-server*' | grep '^.i'
ii openssh-server 1:7.4p1-10+deb9u2 amd64 secure shell (SSH)
server, for secure access from remote machines
Nicht funktionierende Maschine:
root@stretch:~# dpkg-query -l '*ssh-server*' | grep '^.i'
ii openssh-server 1:7.4p1-10+deb9u2 i386 secure shell (SSH)
server, for secure access from remote machines
Also gleiche Version, nur eben ein Mal für i386 (weil das System auch
tatsächlich insgesamt auf 32-Bit installiert ist).
Dass 32- vs. 64-Bit so eine Auswirkung haben soll, wäre aber seltsam. ;-)

Ja, dass die nicht mit Stretch erstellt wurde, mag durchaus sein ...
aber sie ist auf beiden Systemen gleich, wie die MD5-Summe zeigt. Auf
dem einen tut sie wie sie soll, auf dem anderen nicht.
Ebenfalls nochmal zitiert:
root@stretch64vm:~# md5sum /etc/ssh/sshd_config
65326545d54f82d7f93d843447283b04 /etc/ssh/sshd_config
root@stretch:~# md5sum /etc/ssh/sshd_config
65326545d54f82d7f93d843447283b04 /etc/ssh/sshd_config
> root@vmlab:~# cat /etc/debian_version
> 9.3
Funktionierende Maschine:
root@stretchvm64:~# cat /etc/debian_version
9.3
Nicht funktionierende Maschine:
root@stretch:~# cat /etc/debian_version
9.3
