1:0.55ubuntu4.1 timestamps are ahead of the repository

[Dean Sniegowski]

On 12.04.5 64 bit Server, install apt-get is having issues. A search for "ubuntu 12.04.5 hash sum mismatch" will show that I'm not alone with this.

Issue: If you do an apt-get update after a fresh install you'll get

W: Failed to fetch bzip2:/var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_precise_main_source_Sources Hash Sum mismatch
W: Failed to fetch bzip2:/var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_precise_restricted_source_Sources Hash Sum mismatch
<sniped 11 more>

This problem is caused by the time stamps in the apt-setup_0.55ubuntu4.1 package which was updated for 12.04.5
ls -al apt-setup/release-files/archive.canonical.com/precise
-rw-r--r-- 1 root root 5922 Jun 23 2014 Release
-rw-r--r-- 1 root root 198 Jun 23 2014 Release.gpg
But the contents of the Release file shows a date of Thu, 13 Oct 2011 16:32:27 UTC

But on http://us.archive.ubuntu.com/ubuntu/dists/precise/ the files are timestamped for April 2012.
Release 25-Apr-2012 22:49 48K
Release.gpg 25-Apr-2012 22:49 198

When the ubuntu installer does an apt-get update, it does not use the one on the Ubuntu Repo (Apr-2012) because it thinks the one supplied by apt-setup(Jun 2014) is more upto date. Release and Release.gpg are shown as "hit" rather than "get". So apt uses the outdated ones from Apr 2012.

From /var/log/installer/syslog

Because Release is out of date, it break apt-gets update on the 12.04.5 Server and Alternate installs.
Someone just needs to update the dates for Release and Release.gpg in dists/precise.

The dates for Release and Release gpg for precise-backports, precise-proposed, precise-security and,precise-updates are all in 2015.
