There is something wrong with your set up. You haven't really given enough information for anyone to figure it out.
I just yesterday synced Armory 0.92.3 from scratch on a clean install of Ubuntu 14.04.1. It took less than 20 hours start to finish.
This was on an ancient (5+ years old) laptop with a Core2Duo running at 1.8Ghz and 3Gb of RAM. I did, however, replace the HDD with a cheap SSD.
Guess it's not designed to run on low end laptops, like mine:
Intel(R) Core(TM) i5-3317U CPU @ 1.70GHz
4 GB RAM
I should upgrade for armory
