Install latest version on Raspberry Pi

Currently on the Raspberry Pi, the standard

sudo apt-get install arduino

installs a program that labels itself as

Arduino 2:1.0.5

Questions:

  1. Where does the Arduino 2 come in?

  2. I am assuming this is the ARM version of the Arduino software that uses 1.0.5 as its base. Is there a way to install the latest version of Arduino (1.6.7) onto the Raspberry Pi? Apparently some people on the Raspberry Pi forum were able to do so:

https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=92662

but following the same instructions for some reason I was unable to replicate the same results (even with the error tips later in the post).

  1. Even with the Arduino 1.0.5 version, apparently there were issues "Syncing" with the Arduino Uno R3. How do I fix this? Is this a separate issue from Question 2 or can it be fixed by install of the latest version?
