Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies.
mediacenter32 : Depends: libwebkit2gtk-4.0-37 but it is not installable
E: Unable to correct problems, you have held broken packages.

Error: Package install failed!
Error: JRiver Media Center installation from remote repository failed
It still has a dependency in the deb file on a specific version of libwebkit2gtk, so won't take the new one and can't install the one it's demanding. If I'm understanding what I'm seeing correctly, which isn't certain. I think libgtk-3-0 will also be an issue, as it's 4 now. And maybe others.
