Ubuntu App Development. Unable to install Ubuntu SDK and buggy Ubuntu emulator
Hello I have installed Ubuntu 14.04.1 and I have no more patience to struggle with my problem. I can't install ubuntu-sdk package:
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
ubuntu-sdk : Depends: ubuntu-sdk-libs-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I really is unable to solve this problem (unfortunately, solutions listed here don't help me). After my researching I understand that the next generation of Ubuntu apps will use QML language and therefore I need Qt compilers and IDE. The next step was install not Ubuntu-sdk (created on top of Qt Creator), but just Qt Creator. Thank God I installed Qt Creator from official site without any problems. But now I don't know how to use it in creating Ubuntu apps (generally speaking, I'm newbie in creating apps)
So my next step was to install ubuntu-emulator to see how Ubuntu Touch looks like at least. After emulator installation and instance creation I get the following:
A little excerption from terminal:

The emulator is very slow (I work on my HP laptop) and buggy. I assume that the reason of buggy view is in video drivers and may be something relating with OpenGL, I don't know... I will create an additional question regarding this issue
Solution 1:
To fix installing the SDK first install ubuntu-sdk-libs-dev
sudo apt-get update
sudo apt-get install ubuntu-sdk-libs-dev
Then install the sdk:
sudo apt-get install ubuntu-sdk
