while installing python2.6 getting error on ubuntu 12.04
<p>"I am using ubuntu 12.04 and by default python 2.7 is installed .I want python 2.6 .
When I used 
apt-get install python2.6
I am getting error 
Reading package lists... Done

Reading state information... Done
Package python2.6 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  python-gdbm</p>

<p>E: Package 'python2.6' has no installation candidate</p>

<p>Thanks in advance."</p>
