[Bug 582251] [NEW] debug1: Remote: No xauth program; cannot forward with spoofing.

[arturj]

Public bug reported:

Fresh installation of a LUCID server (AMD64) has following major issue:

X11Forwarding does not work anymore. Running the ssh-client (again from
Lucid Desktop) like this "ssh -v servername" throws:

...
debug1: Remote: No xauth program; cannot forward with spoofing.
...

Running "strings /usr/sbin/sshd |grep xauth" on the remote server shows that sshd is looking for xauth in this path:
/usr/bin/X11/xauth

But this does NOT exist until the package "x11-common" is installed.

Hint: Package "xauth" which is automatically installed by openssh-server
has its binary in "/usr/bin".

Suggestion: SSHD should be fixed to look for xauth in the right
directory or openss-server package should be fixed to depend on
x11-common package instead xauth

There are many other X11-Forwarding bug reports - maybe related to this
issue.
