[Marc Dequènes (Duck)]

Coin,

Quoting Vincent Bernat <bernat at debian.org>:

Apache tries to yes:

2001:7a8:810:6969:21f:d0ff:fe8f:cfec] Symbolic link not allowed or

And as you can see, the css symlink is not working either.

Why misleading?

Yes.

But it does not here.

I get a 403, see log entries above.

I'm using a dedicated vhost, but was using /usr/share/roundcube.

It seems i missed the change in the changelog in 0.5.1-1 « Rework how  
symlinks work. ». Nevertheless, after changing the directory, it does  
not work better.


I had another look at the problem. When building your package i get  
(using debc):
lrwxrwxrwx root/root         0 2012-02-05 19:06  
./var/lib/roundcube/plugins/jqueryui ->  
/usr/share/roundcube/plugins/jqueryui
In my system, it is not a symlink, but a directory. I may have done a  
mistake earlier, so i moved /var/lib/roundcube/plugins/jqueryui away,  
before upgrading to 0.7.1-1. This file is then recreated
 as a  
directory!

Looking a bit further, i can see /usr/share/roundcube/plugins should  
be a directory, but in my system is a symlink to  
/var/lib/roundcube/plugins.

It really seems the migration to the new symlink layout did not work  
correctly on my system :-(.
