Hi Jussi,

Jussi Kuokkanen via Bug reports for GNU Guix <[email-masked]> skribis:

> I'm getting a "Cannot make/remove an entry for the specified session" after logging into the installed system, which returns me to the login prompt. The cause seems to be shepherd failing to start dbus, which PAM depends on. System config file and logs as attachments.

[...]

> Aug 26 15:14:04 localhost login[203]: pam_unix(login:session): session opened for user jussi by LOGIN(uid=0)

It seems that there’s at least one serious problem, which is
/var/run/dbus/system_bus_socket is unavailable, for some reason.

Did the ‘dbus-system’ shepherd service start correctly, or did you get
messages suggesting otherwise?

Thanks,
Ludo’.
