/dev/tty problem

Hej!

Blir smått galen på tty som krånglar på en nyistallerad testing maskin.

/etc/init.d/samba start:
[....] Starting nmbd (via systemctl): nmbd.serviceError creating textual
authentication agent: Error opening current controlling terminal for the
process (`/dev/tty'): No such device or address (polkit-error-quark, 0)
. ok
[....] Starting smbd (via systemctl): smbd.serviceError creating textual
authentication agent: Error opening current controlling terminal for the
process (`/dev/tty'): No such device or address (polkit-error-quark, 0)
. ok
[....] Starting samba-ad-dc (via systemctl): samba-ad-dc.serviceError
creating textual authentication agent: Error opening current controlling
terminal for the process (`/dev/tty'): No such device or address
(polkit-error-quark, 0)
. ok


ls -l /dev/tty:
crw-rw-rw- 1 root tty 5, 0 dec 24 21:08 /dev/tty


Har googlat men inte hittat något vettigt svar.
Är det någon som har någon idé om vad problemet beror på.

Mvh Erik
