there really wont be a "should" for this, just, what works for you. why do
you need a newer version of guitarix? why not use the "supported" version
in the ubuntu repos? is there a feature you need in the latest? if so, i
would ask the maintainers/creators what is needed, and comply. nothing
about ubuntu 14.04, or any of the versions is preventing guitarix from
working specifically, but, ubuntu is not a "rolling release".

nothing is really "broken" to be fixed here, which is the issue. you are
trying to use a package that is not an ubuntu system package, and it can be
challenging to address all the dependencies and needs manually.

what would i do? likely just elaborate about what i want/need from the
latest version of guitarix, and see if there is a simple PPA that i can add
to my 14.04 system to add the package. if not, i would elaborate about what
is needed. i personally wouldnt be bothered by removing ardour, since, i
prefer to pay for the binary directly from the ardour site, and get the
latest from them directly. with FOSS and linux, there is always some kind
of answer. you could go as far as another system in chroot that supports
*exactly* what the creators of guitarix say you need.. but, i wouldnt get
too technical on this.. i would see if there is actually anything from
guitarx's latest version you need, and go from there..
