I would recommend that you check if the install is successful and run aptitude
update if its not. If a updated package is published since you ran "aptitude
update" you will get a 404 on your request for the older version. I think this
would be the most elegant thing to do, instead of failing to install the
package on every run until the packet database gets updated.
