Thanks for pointing this out. After much trial-and-error, I settled for using this as the contents of my `preferences` file: Package: /^r-/ Pin: release n=stretch Pin-Priority: 995 Now, when I run `apt-get dist-upgrade`, the proposed changes make more sense to me. But, WARNING to anyone who comes across this post: Use the above configs at your own risk. This is (still!) all voodoo to me, unfortunately. Even after having read the documentation, it still happens with distressing frequency (maybe a third of the time?) that `apt-get` proposes actions that make absolutely no sense to me. IOW, I hardly understand `apt-get` at all. Best, kj
