How can I install Qt version 4.8.1 in Kubuntu 14.04?

I cannot find the version 4.8.1 in the official Qt site's downloads list. Kindly help me to install the exact version.

You will have to first download the source from here for qt 4.8.1.
Then open a terminal(Ctrl+Alt+T) and goto the path where you have download the file.

Install the required dependencies

sudo apt-get install build-essential checkinstall

Then extract the file using 

tar -xvzf qt-everywhere-opensource-src-4.8.1.tar.gz

Then goto the extracted folder using 

cd qt-everywhere-opensource-src-4.8.1

and run

  1. ./configure
  2. make
  3. sudo checkinstall

This will make a .deb of the source you can install as a normal application via apt

sudo dpkg -i path/to/output.deb

Change path/to/output.deb to the path of the created .deb file.
