Running Adb On Ubuntu 11.10 Results Permission Denied

I've searched a lot of resources for this problem but none of them helped. So, I've followed this steps http://developer.android.com/guide/developing/device.html#setting-up and aft

Solution 1:

I copied the folder of the android sdk to /home/<user>, and for the problem with:

no such file or directory

I installed the ia32-libs by using apt-get install ia32-libs. Its basically because of some incompatibility.

Thanks.
