Responses to many things in this thread:

- Until I fully test the CRAN site, I strongly suggest using the PPAs 
that feed the CRAN site.




I prefer to use the PPAs personally, as one apt-add-repository command 
adds the repository and the gpg key with no chance of typos.  Easy to 
remove,  as well.

- For Xenial (16.04), I failed to build r-cran-nnet, which is why 
r-recommended won't install.  It is trying to use r-cran-nnet built 
against R 3.6, which is why it fails.  That has been fixed, and should 
be available after the next sync.

- I have updated the README, thanks for correction.  Again, change 
should appear on the next sync.

- The process of building the repository on CRAN has a lot of moving 
parts, mostly of my own doing.  When a new major version is released, it 
takes some time to create the repository and test it.  Part of the issue 
that the repository is synced twice a day, so it takes time for changes 
to propagate and to test it.  Different mirrors will have different 
contents, so it may work on cran.r-project.org but not on 
cloud.r-project.org for a couple of hours.

I try not to break things, but sometimes a small bug creeps in.  My 
apologizes for that.

When I have tested all the releases to ensure they all work, I will 
announce it on this list-serv and on twitter.  Hopefully, I will have 
this finished by the end of the day.
