After installation problem.

Hi, i have Aegir runnig, but when i want upgrade my server Ubuntu 10.04 i can't :

apt-get upgrade -> return:

You should run "apt-get -f install", to fix them. The following packages have unmet dependencies: aegir2: Requires: aegir2-provision (>= 2.0) but is not installed aegir2-hostmaster: Requires: drush (>= 5.5) but is not installed Wymaga: aegir2-provision (>= 2.0) but is not installed

apt-get -f install -> is not much helpful.

My server insformation: Ubuntu 10.04 Drush Version : 6.2.0 (installed by using this command: sudo pear install drush/drush) My drush location: /usr/share/php/drush My aegir provision location: /var/aegir/.drush/provision

How to fix this problem?
