Please be careful with upgrades to R 3.4.2. To cut a long story short, this has to do with minor internal changes in R 3.4.0 from April which require _some_ packages to be rebuilt. I argued for that approach (ie: incremental, careful, no side effects) within Debian, and lost. The _official_ packages in Debian now carry a new tag r-api-3.4 (as opposed to previous r-api-3) in order to force clean updates with matching packages.
But matching packages is the key. _Everyting_ needs to be rebuilt. We will get there. In the meantime, do not install an r-base-core providing r-api-3.4. I failed to give Michael a heads-up so the PPA builds he so promptly provides carried this for a moment. I am right now rebuilding R 3.4.2 in my PPA with a r-api-3 tag for transition. Those should work once we have zesty, yakkety, xenial, trusty, ... images as needed. Michael and I will figure out how and where to go from here to meet that requirement of r-api-3.4 with limited disruption. Thanks to Jeroen for crying wolf on Twitter, as little as I like to discuss issues there it is still a good news beacon. (And for now mailing here too.) I'll post updates. Working with r-api-3, and of course paying attention to what apt tells us should work fine. "Should".
