Site install fails with Aegir I've been using Aegir to install Atrium sites without a hitch. Users self register through Aegir to spawn their own open atrium sites. Today I noticed new atrium sites failed to install. A week ago this worked fine and as far as I know nothing has been changed with core content/modules. I did some comparisons in looking at the task log between the failed install and a successful install (from a week ago). The simplexml load and "Could not download project status information" is weird. Here's what I gathered so far. Task install log looks identical until near the end. The failed install shows the following after "downloading release history…": 

Downloading release history from http://updates.drupal.org/release-history/drupal/6.x
simplexml_load_file(): 6.x:2: parser error : Specification mandate value for attribute http-e pm.drush.inc:2103
simplexml_load_file(): s="http://www.w3.org/1999/xhtml"&gt;

simplexml_load_file(): ^ pm.drush.inc:2103
simplexml_load_file(): 6.x:12: parser error : Opening and ending tag mismatch: p line 11 and body pm.drush.inc:2103


This goes on for several more lines - finally ending in the following error:

Could not download project status information from http://updates.drupal.org/release-history/drupal/6.x


This compares to This compares to the successful site task install log here:

Downloading project drupal to /tmp/drush_tmp_1368706259 ...
Downloading drupal-6.28.tar.gz was successful.
Md5 checksum of drupal-6.28.tar.gz verified.

The diff analysis looks similar again for many more lines, then shows the following error for the failed install log:

WD form: Illegal choice 5 in Roles allowed to use this profile element.
WD form: Illegal choice 6 in Roles allowed to use this profile element.


The rest of the task log for the failed install shows typical Aegir behavior of dropping the database and deleting directory.Searching through my general site logs, or when I run cron, I get

"Unable to fetch any information about available new releases and updates."
I also get that error when I try to manually run cron 
Also a few other things like:

Warning: include() [&lt;a href='function.include'&gt;function.include&lt;/a&gt;]: Unable to allocate memory for pool. in theme_render_template() (line 1079 of/var/www/vhosts/site.com/hostmaster-6.x-1.4/includes/theme.inc).

An illegal choice has been detected. Please contact the site administrator.


The "unable to fetch information about new releases..." error is weird and similar to the Aegir error on the failed install task log. 
Unfortunately I don't know where to start. I'm wondering if this is a write permissions issue with drush, or php version issue. It;s starnge that it's happened suddenly, so maybe Aegir changed something on the fly. Don't know... Any thoughts? Thanks!
This line says it all:
    Could not download project status information from http://updates.drupal.org/release-history/drupal/6.x

Probably not a problem you or Aegir could do anything about. Just an Internet hickup.
