new Ubuntu 12.04 supports only python 2.7 or newer and from repositories you can install only blender 2.62, but this version doersn't work with m2mod and m2i import/export plugin
to use old 2.49b blender we need to install old python2.5
we will use an external repo
open a terminal and type this line to add this new repo:
$ sudo add-apt-repository ppa:fkrull/deadsnakes
now we need to update apt list, type:
$ sudo apt-get update
now we can install old python
$ sudo apt-get install python2.5 python2.5-dev
now python2.5 is installed
download blender2.49b and extract it in a folder
