Yes, one cannot use Drush to download Provision since we no longer are making releases on drupal.org. You have found a bug, please file a report in the Hostmaster issue queue if you can?
I thought I fixed this to use wget to grab Provision, but perhaps I didn't commit it :/
A workaround for you (and what the UPGRADE.txt ought to say) is to wget Provision from http://files.aegirproject.org/provision-0.4-alpha5.tgz and put it /var/aegir/.drush/
the current upgrade.txt says to update provision to use drush to download it
the way i see it, there are 2 options
update the documentation
or simply release the updated tar.gz file on D.O to allow drush to play nicely
the second would be preferred, even if you are not using CVS for module development

anarcat commentedI'm not sure we'll go through the trouble of publishing provision on d.o, especially since we can't publish it's frontend counterpart (because it's all crammed up in one chunk).
The instructions were fixed, do you think we should publish to drupal.org?

mark trappA publish for UPGRADE.txt to d.o, or at least changing the link on g.d.o (see http://groups.drupal.org/node/47784) would be helpful. I got stuck following UPGRADE.txt found on g.d.o until i started going through the issue queue here to find this.

anarcat commentedI fixed the link for the UPGRADE.txt to point to the updated docs.
