I am trying to install a software package through the ubuntu software centre but I am getting this error:-
The following packages have unmet dependencies:
gnome-control-center: Depends: libxi6 (>= 2:1.2.99.4) but 2:1.7.1.901-1ubuntu1.1 is to be installed Depends: gnome-control-center-data (>= 1:3.6.3-0ubuntu56.1) but 1:3.6.3-0ubuntu56.1 is to be installed
unity-control-center: Depends: libpulse-mainloop-glib0 (>= 1:0.99.1) but 1:4.0-0ubuntu11.1 is to be installed Depends: libpulse0 (>= 1:0.99.1) but 1:4.0-0ubuntu11.1 is to be installed Depends: libxi6 (>= 2:1.2.99.4) but 2:1.7.1.901-1ubuntu1.1 is to be installed
I have tried following the steps on How do I resolve unmet dependencies after adding a PPA? but I can't seem to upgrade/fix this one particular package named 'libgbm1' . I can't even remove it and the output goes:-
The following packages have unmet dependencies:
indicator-bluetooth : Depends: unity-control-center but it is not going to be installed or gnome-control-center but it is not going to be installed or ubuntu-system-settings but it is not going to be installed
libqt5gui5 : Depends: libgbm1 (>= 8.1~0) but it is not going to be installed libubuntu-application-api-mirserver1 : Depends: libmirserver18 (>= 0.1.8+14.04.20140408.1) but it is not going to be installed libunity-mir1 : Depends: libmirserver18 (>= 0.1.8+14.04.20140411) but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
I am still a new ubuntu user and didn't really wish to go un-installing the control centres without knowing the repercussion. Does anyone know what I should do from here?
