I'm trying to install Civi 4.6 with Drupal 7, using the instructions in the wiki page referenced in the title. In step 2, it says:
As administrator in Drupal, go to Modules, click on Install New Module, and it will ask you to fill in the URL of the module. It will then fetch it and install it for you. You will need to enable the Update Manager module in the drupal modules page to see the Install New Module link.
The current link is http://sourceforge.net/projects/civicrm/files/civicrm-testing/4.6.alphax/. You will need to replace 4.6.alphax with the current minor version number.
Hit the Install Button.
Apparently the current minor version is alpha1, so I enter http://sourceforge.net/projects/civicrm/files/civicrm-testing/4.6.alpha1/, and hit Install. I get:
Cannot extract temporary://update-cache-b2aa7d22/4.6.alpha1, not a valid archive.
Maybe I should add that I'm trying to install this on my account at the web host webfaction.com. Not sure if this makes any difference.
