I was and am new to linux so I couldn’t exactly follow the instructions on installing Scrivener onto Ubuntu/Kubuntu (figuring out what code to change). I found these instructions helpful for installing from a deb file: http://community.linuxmint.com/tutorial/view/370 with the relevant code posted right below.
To get a 32-bit library (this takes a few minutes since it was a 277mb download for me):
sudo apt-get install ia32-libs
Here you just change the directory to the location of your deb file. I actually just right-clicked on the deb file and selected “open in terminal”:
cd 'Folder Location'
Then you force linux to put Scrivener in its own 32-bit environment. I’m posting the original but that didn’t work for me. I had to use code from a user-comment which is posted below the original.
Original (which didn’t work for me):
sudo dpkg -i - -force-architecture package.deb
What worked for me:
su -c "dpkg -i --force-architecture package.deb"
