Comment 28 for bug 595116

Confirmed the fix - we no longer see any errors saying " request failed: error reading the headers" - and all the web pages work as expected. I searched the internet for weeks looking for that message, and failed, until I added ubuntu to the search - and found this thread - this was a huge fix for us - thank you.

For anyone looking to fix the same issue, here are the steps I used:

echo "deb http://archive.ubuntu.com/ubuntu/ lucid-proposed restricted main multiverse universe" >> /etc/apt/sources.list

cat > /etc/apt/preferences
Package: *
Pin: release a=lucid-security
Pin-Priority: 990

Package: *
Pin: release a=lucid-updates
Pin-Priority: 900

Package: *
Pin: release a=lucid-proposed
Pin-Priority: 400

(control-D to end)

Then
aptitude install apache2/lucid-proposed

Don't pick the first solution, but instead pick the following one:

Upgrade the following packages:
apache2-mpm-worker [2.2.14-5ubuntu8.2 (lucid-updates, lucid-security, now) -> 2.2.14-5ubuntu8.3 (lucid-proposed)]
apache2-threaded-dev [2.2.14-5ubuntu8.2 (lucid-updates, lucid-security, now) -> 2.2.14-5ubuntu8.3 (lucid-proposed)]
apache2.2-bin [2.2.14-5ubuntu8.2 (lucid-updates, lucid-security, now) -> 2.2.14-5ubuntu8.3 (lucid-proposed)]
apache2.2-common [2.2.14-5ubuntu8.2 (lucid-updates, lucid-security, now) -> 2.2.14-5ubuntu8.3 (lucid-proposed)]

Score is 53

Then the install will show:

The following packages will be upgraded:
  apache2 apache2-mpm-worker apache2-threaded-dev apache2.2-bin apache2.2-common

Now be sure you have the right stuff:

root@ubuntu:/etc/apt# dpkg -l | grep apach
ii apache2 2.2.14-5ubuntu8.3 Apache HTTP Server metapackage
ii apache2-mpm-worker 2.2.14-5ubuntu8.3 Apache HTTP Server - high speed threaded model
ii apache2-threaded-dev 2.2.14-5ubuntu8.3 Apache development headers - threaded MPM
ii apache2-utils 2.2.14-5ubuntu8.2 utility programs for webservers
ii apache2.2-bin 2.2.14-5ubuntu8.3 Apache HTTP Server common binary files
ii apache2.2-common 2.2.14-5ubuntu8.3 Apache HTTP Server common files

If you see 8.3, then you have the new code... Thanks again.
