얼마전 Ubuntu 12.04에서 14.04 (정확히 14.04.2) 로 바꾸었는데,
libgl1-mesa-glx 를 설치할때 설치가 아래의 오류로 설치가 불가능한 이슈가 발생했다.
The following packages have unmet dependencies:
libcheese-gtk23 : Depends: libclutter-gtk-1.0-0 (>= 0.91.8) but it is not going to be installed
Depends: libcogl15 (>= 1.15.8) but it is not going to be installed
libcheese7 : Depends: libclutter-gst-2.0-0 (>= 0.10.0) but it is not going to be installed
Depends: gstreamer1.0-clutter but it is not going to be installed
libclutter-1.0-0 : Depends: libcogl-pango15 (>= 1.15.8) but it is not going to be installed
Depends: libcogl15 (>= 1.15.8) but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
관련 이슈가 아래 링크에 리포트되어 현재는 수정된 듯.

14.02.2 배포버전으로 갈아탄 나로서는 급한대로 #24에 언급한 workaround 방식으로 해결.
