I am trying to install python 3.2.3 on my ubuntu machine, which is 12.04, but I do not want to disturb the current 2.7 installation. After searching on the internet, I found a reference here. I followed the instructions, but when trying to run
sudo apt-get install build-essential libncursesw5-dev libreadline5-dev libssl-dev libgdbm-dev libc6-dev libsqlite3-dev tk-dev
I get an error saying that
E: Package 'libreadline5-dev' has no installation candidate.
What am I missing? Is there any other way to install python 3.2 on ubuntu? If I use apt-get, will it disturb the current installation?
