Hm... ‘Jessie’ is a release of not unkindred, yet _another_ GNU distribution — Debian. Despite experience suggests, that itʼs certainly possible to install software built for one distribution on another (commonly the other way round: so called PPAs from launchpad.net are for Ubuntu, yet are usable on Debian), I would definitely avoid doing that in your case — why? > but I'm a bit scared to do something similar with "newer" sources in fear of > breaking system-wide dependencies… I do not think, there is anything to fear. aptitude(8) just wonʼt let you to install packages with broken dependencies or those which break dependencies. And if all dependencies will happen to be satisfied (I strongly doubt it), then it should be usable. > Any help would be much appreciated. You might want to try to build it from sources (in normal meaning of that word) from a newer Ubuntu release. Cf. apt-build(1).
