problem with dependencies while installing ubuntu-sdk

I get this error while installing ubuntu-sdk on clean install of Ubuntu
13.04 64bit:
szymon@szymon-PC:~$ sudo apt-get install ubuntu-sdk
[sudo] password for szymon:
Reading package lists... Done

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: qtcreator-plugin-ubuntu but it is not going to be
installed
Depends: qtcreator-plugin-ubuntu-cordova but it is not going
to be installed
E: Unable to correct problems, you have held broken packages.
Any ideas ?
