1. Wait for it to enter vivd-updates. Now that it's been confirmed, this should happen soon.
2. Forcibly install it from vivid-proposed together with the libglib2.0-0 updates that it wants.
For #2, the command in question should be something along the lines of "sudo apt-get install banshee/vivid-proposed libglib2.0-0/vivid-proposed libglib2.0-bin/vivid-proposed". I haven't tested this command, but I think it should work.
Otherwise, you could try to disable the pin that causes vivid-proposed to get a lower pin-priority in apt. This will cause a flood of -proposed changes (which may or may not introduce regressions), so I advise against this approach.
There are two approaches you can take for this:
1. Wait for it to enter vivd-updates. Now that it's been confirmed, this should happen soon.
2. Forcibly install it from vivid-proposed together with the libglib2.0-0 updates that it wants.
For #2, the command in question should be something along the lines of "sudo apt-get install banshee/ vivid-proposed libglib2. 0-0/vivid- proposed libglib2. 0-bin/vivid- proposed" . I haven't tested this command, but I think it should work.
