OoO  Pendant le repas  du dimanche  05 février  2012, vers  19:50, "Marc

Because    it    would    appear     that    it    tries    to    access
/var/lib/javascript/jquery-ui/jquery-ui.min.js  (which  does not  exist)
while in fact there is an intermediate symlink:
 lrwxrwxrwx 1 root root 37 déc.  26 21:50 /var/lib/roundcube/plugins/jqueryui -> /usr/share/roundcube/plugins/jqueryui

Therefore, the above symlink works.

The  correct  directory  has   always  been  /var/lib/roundcube  but  we
previously arranged  so that /usr/share/roundcube would work  too but it
was getting quite complicated. I  am unsure when we removed the symlinks
From /usr/share/roundcube  to /var/lib/roundcube.  I would say  this was
for 0.3.

That's quite surprising because it is the job of dpkg to work with those
symlinks. I will  try to find which version had symlinks  in the old way
and test an upgrade.
