mpv-build-deps breaks apt-get on Ubuntu 14.04.2 about mpv-build

[kevmitch]

Works for me in my trusty chroot with /etc/apt/sources.list

deb http://mirror.its.sfu.ca/mirror/ubuntu trusty main restricted universe multiverse
deb http://mirror.its.sfu.ca/mirror/ubuntu trusty-updates main restricted universe multiverse

A lot of the dependencies are in universe, some maybe even in multiverse. Do you have these repositories selected? You can see/change with the software-properties-gtk GUI.

Yeah they're definitely selected. Its a 14.04.2 issue, so it might not apply to your setup unless you've opted in to the update. Turns out the root of the problem is certain dev packages not having resolved dependencies in 14.04.2, which is not an mpv issue. The fact that installing this package completely breaks apt-get until its uninstalled is still kind of worrying though. Not sure if there's anything to be done about it though, so unless someone thinks otherwise there's probably no reason for this to stay open any longer.

I'm not exactly sure how Ubuntu handles their point releases. I had assumed that having trusty-updates selected would include that. What does your sources.list look like?

Do you know which packages are causing the problem? Unfortunately, apt is really bad about telling you what the actual problem is in the case that one of the dependencies is unsatisfiable. You typically have to try installing the dependencies one by one without the mpv-build-deps package until you encounter the problem.

If a package with unsatisfied dependencies is installed, then yes apt will complain / possibly not work until that's either resolved or the package is uninstalled. That's just the way apt works. I'm sure some would argue it's a feature not a bug.

fixed in ubuntu
