Ubuntu PPA depends on alethzero and mix-ide

[eltonmelo21]

The installation guide at http://www.ethdocs.org/en/latest/ethereum-clients/cpp-ethereum/installing-binaries/linux-ubuntu-ppa.html presents the following instructions:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install cpp-ethereum

However, the last command fails due to dependencies:

$ sudo apt-get install cpp-ethereum

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

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 cpp-ethereum : Depends: alethzero but it is not going to be installed
                Depends: mix-ide but it is not going to be installed

I followed this: https://ethereum.stackexchange.com/questions/1614/whats-the-difference-between-eth-and-cpp-ethereum

Install was successful, but trying to run without any args, I keep getting:

this probably needs to go to the cpp-ethereum issues

I've got the same issue here.
