I got it by private messaging the original poster.
To install it on a 64bit version of Ubuntu run the following from the command line:
Code:
sudo dpkg -i --force-architecture kobo-desktop.deb
That should overcome the architecture error, if you get any errors about missing libraries then you may not have the 32bit libraries installed so run:
Code:
sudo apt-get install ia32-libs
I agree it is a little weird that they don't seem to have even the Windows & Mac versions of the software on their website. I don't think they're ready to "support" the Linux version through their tech support people yet so I wouldn't expect to find that there yet.
