I'm using Ubuntu 12.04 32bit. Today, suddenly some updates had arrived but it wasn't normal update. It said me to partial update. When I have done this, update manager want to remove vlc. I did it. But when I want to install vlc from synaptic package manager, I found broken dependencies there. Now, If I want to install vlc from Software Centre, It pops up: The following packages have unmet dependencies: vlc: Depends: fonts-freefont-ttf but it is not going to be installed Depends: vlc-nox (= 2.0.3+git20121005+r392-0~r42~precise1) but 2.0.3+git20121005+r392-0~r42~precise1 is to be installed Depends: libavcodec-extra-53 (= 4:0.8-1~) but 4:0.8.3ubuntu0.12.04.1 is to be installed Depends: libavutil-extra-51 (= 4:0.8-1~) but 4:0.8.3ubuntu0.12.04.1 is to be installed Depends: libc6 (= 2.15) but 2.15-0ubuntu10.2 is to be installed Depends: libfreetype6 (= 2.2.1) but 2.4.8-1ubuntu2 is to be installed Depends: libgcc1 (= 1:4.1.1) but 1:4.6.3-1ubuntu5 is to be installed Depends: libqtcore4 (= 4:4.8.0) but 4:4.8.2+dfsg-2ubuntu1~precise1~ppa1 is to be installed Depends: libqtgui4 (= 4:4.7.0~beta1) but 4:4.8.2+dfsg-2ubuntu1~precise1~ppa1 is to be installed Depends: libstdc++6 (= 4.6) but 4.6.3-1ubuntu5 is to be installed Depends: zlib1g (= 1:1.2.3.3.dfsg) but 1:1.2.3.4.dfsg-3ubuntu4 is to be installed Hey, Now what to do?
