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 https://launchpad.net/ubuntu/+source/bowtie2/2.2.4-2. There are 3 files at the bottom, which one should I download, how to install in ubuntu?


  • You could add that launchpad as ppa source to your apt-get sources list. Does that page list packages for your Ubuntu version ? Aug 3, 2016 at 22:47
  • and by the way, what is your version Aug 3, 2016 at 22:47
  • If you can't even tell those 3 files apart, are you really sure you want to download a source code archive for an unsupported Ubuntu release, modify it to work on your current release and then manually compile the package yourself? Besides, Ubuntu is not Unix!

There is a .deb package of that version here

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

wget http://launchpadlibrarian.net/190682664/bowtie2_2.2.4-2_amd64.deb

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...

  • Great, the deb file is what I want, Thanks a lot.

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.
