Solving problems with python-dev package installing hplip 3.14.6 on Ubuntu 12.04.4

I found that the latest update of Ubuntu 12.04.4 does not include precise-updates and this is necesary to install the latest hplip 3.14.6


Just add these lines to /etc/apt/sources.list

deb http://mx.archive.ubuntu.com/ubuntu/ precise-updates main restricted universe multiverse
deb-src http://mx.archive.ubuntu.com/ubuntu/ precise-updates main restricted universe multiverse

Solving problems with ncomputing in Ubuntu 12.04

Using synaptic package manager (sudo apt-get install synaptic) I was able to find the Xorg meta package which is listed as "Xorg" then by going to the "packages" menu at the top of synaptic, drop down, and select force version. I had my luck with the older version " 1:7.6 12ubuntu1 (precise) "
Synaptic will warn you that it is removing and installing a bunch of packages. That's just the downgrade of all the packages comprising the xorg meta. We end up with what's likely what the nc modules are built against, so everything seems to work fine.

Hopefully this helps until nc can update the installer.
