OPKG update after arduino dock flashing

[Ary Vinicius Nervis Frigeri]

I'm a new user in Omega World. I was flashing the arduino dock when i realized that i forgot to install the py-serial module. So i tried to run the comand opkg update and after opkg install ...
So i got an error : "Package arduino-dock version 0.1-1 has no valid architecture omega"

How can i deal with this?

I've reset the omega to factory defaults, but i guess there´s another way to deal with this.

Versions of your Omega, your Arduino Dock, what did you "flash" that Dock ... so any info about your config would be great.
BTW if you have an Omega2(+) and an Arduino Dock 2 then you should install the arduino-dock-2 package.
