how to download package from https://launchpad.net/ubuntu? example inside

I'm beginner for Unix. I can use "sudo apt-get install...." to install the package, but it is not the version I need(too new), that why I need to find and download an older version from other place.

I want to download the package from . There are 3 files at the bottom, which one should I download, how to install in ubuntu?

There is a .deb package of that version here

You can click the .deb file to download it or do this:

wget 

And then make sure you have the dependencies:

sudo apt-get install libc6 libgcc1 libstdc++6

(probably all newest version already)

Then install:

sudo dpkg -i bowtie*

but this old version may not work well on your system and won't be updated...

At the bottom of the page it says "Binary packages built by this source" and there you should click the "Bowtie2" link. On the page which follows is shows 3 versions to select from, so choose the 2.2.4-2 option. The next page has, at the upper right corner of the window "Downloadable files" and there you want to click "bowtie2_2.2.4-2_amd64.deb" which will download the installable package. Have Gdebi install it and there you go.
