For those who might come across this issue, I was able to workaround it and install things by manually specifying all the needed dependencies.
sudo apt-get install libgles2-mesa-dev libegl1-mesa-dev libwayland-dev qtbase5-dev Should this occur in the future, you likely can build a similar string of depends that apt isn't picking up on and install them together. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1435324 Title: qtbase5-dev not installable on Ubuntu 14.04 LTS Status in apt package in Ubuntu: Confirmed Status in mesa-lts-vivid package in Ubuntu: Confirmed Status in qtbase-opensource-src package in Ubuntu: Incomplete Bug description: I discovered the problem when I tried to compile a Qt5 QML program firstly. I have an Ubuntu 14.04.2 LTS with all updates, no significant PPAs (only nodejs and owncloud, not affecting this problem here) and with all the -lts-utopic upgrade packages installed. With that system, I tried to install qtbase5-dev, and apt told me: [...] The following packages have unmet dependencies: qtbase5-dev : Depends: libgles2-mesa-dev or libgles2-dev but it is not installable 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. So this package seems to be not installable. This tried in synaptic, it tries to uninstall all -lts-utopic packages (inclusive all xserver*.deb) and install the "old" ones instead of them. So the problem somewhere lies within the new lts packages that seem not to be compatible with qtbase5-dev (and its dependency: libgles2 -mesa-dev - but I am not able to find out further. The problem is: Qt5 development on an Ubuntu 14.04.2 LTS machine is NOT possible without a fix. The make process always complains about not finding gl libraries.
