Have been trying to install Gnuradio for several days and keep having trouble with qt4 not building/installing properly. Seemed to depend on a thing named 'unity-control-center' which claimed to be dependent on two libraries, both of which claimed to be up to date. This is what I got if I tried to install just qt4. Get exactly the same unmet dependencies if I try to install any qt4 app from the Software Center, FWIW.
ftoewe@ftoewe-Inspiron:~$ sudo apt-get install qt4-dev-tools libqt4-dev libqt4-core libqt4-gui Reading package lists... Done Building dependency tree Reading state information... 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: unity-control-center : Depends: libcheese-gtk23 (>= 3.4.0) but it is not going to be installed Depends: libcheese7 (>= 3.0.1) but it is not going to be installed E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. ftoewe@ftoewe-Inspiron:~$
Asked for help a couple of days ago and got messed up trying to complete a suggestion. So back trying again. Thanks in advance.
