HowTo: Create a list of installed packages

[oldfred]

@Muhammad_Ahmad_Mujtaba
How old was old install? Often a few packages are not in new version, or you may have had old packages not marked obsolete in your old install.

You will have to research each package. I would copy an paste into synaptic as it often has a bit more info.
sudo apt-get install synaptic

In synaptic in my 12.04 I do see xtrans-dev as a package, but not currently running 14.04 to check there.
