I'm currently packaging primarily for 16.04.

As of October 24th 2016, I'll only be packaging for 14.04 if it's an easy or no-change update.

Be aware that some backports are built against newer GCC and binutils (ppa:jonathonf/gcc). To check, look under "Technical details about this PPA" for the presence of "GCC". (FYI, that PPA might also useful for running the Liquorix kernel)

Remember that most packages built for Xenial will work just fine on newer releases too.

Please consider donating to Debian and the Ubuntu Community. The packages in these PPAs wouldn't exist without them:

If you have any requests beyond what I already provide I'm open to persuasion, or if you want to send anything my way in appreciation:

Note: I do not run any non-LTS (e.g. zesty/17.04) or non-x86 systems. If you'd like a package for those, see above. :)
