Hi Jimi, I have a similar problem. I fix it by reinstalling gdal (libgdal20). I can install QGIS again after that. But, I am not an expert with this package manager thing, so perhaps it can work for you also, or perhaps not :)
While trying to fix my problem, I found this https://askubuntu.com/questions/140246/how-do-i-resolve-unmet-dependencies-after-adding-a-ppa which probably useful for you.
