You might give MC30 a try and see if it works. The hard truth is that Linux and macOS are less forgiving when it comes to backwards compatibility in regards to older Media Center releases unfortunately, and eventually they won't work anymore on newer Linux distros and macOS. Over time you'll encounter issues like this, either with dependencies being removed completely from a Linux distro or instances where newer Linux distros ship newer versions of dependencies which are incompatible with older Media Center versions.
This issue was fixed during the MC29 development cycle, as libpangox was removed in Debian's and Ubuntu's (which Mint is based on) repositories nearly a year ago. You can try forcing the package manager to ignore the missing dependency (e.g. sudo apt-get --ignore-missing install mediacenter27 in a terminal), I've never tried this and it may not even work anymore so your results may vary there.
