The problem is file permissions, which by default don't allow you to install extensions with the privileges of the web server.

We fixed this in the upcoming release, but we are still working out the final bugs, so try this workaround in the meantime: 

chown -R www-data:www-data /usr/share/joomla15
chown -R 4755 /usr/share/joomla15
Thanks for the feedback!
