R SIG Debian - May 2020 - c2d4u3.5 ppa for Ubuntu 20.04?

Hi

I tried to use Michael's ppa after having installed Ubuntu 20.04 and R 4,
and it seems the ppa is not available now for 20.04, I get message: The
repository 'http://ppa.launchpad.net/marutter/c2d4u3.5/ubuntu focal
Release' does not have a Release file

Am I doing something wrong, or is it correct that it is not available yet?
Are there any plans to implement it at some point?

Thanks!!

I haven't really had a chance to test it, which is why I haven't 
officially announced it yet.  Been a busy couple of weeks with the 
semester ending and *other* things.

But you can find c2d4u for 4.0 PPA here:

https://launchpad.net/~c2d4u.team/+archive/ubuntu/c2d4u4.0+

The different user name is because I moved it to a team thinking that in 
the future, more than just myself will want to work on this.  I know it 
works in a controlled environment (a fresh docker container), but I 
haven't really tested moving from a 3.5 to 4.0 situation.   If there are 
issues, let me know.

By the way, Bionic is complete (I think).  About 3/4 of the way through 
Focal and I will start Xenial next week.

The usual README ends in

  For additional binary packages for R (currently 4,000+), check out the
  CRAN2deb4ubuntu PPA: https://launchpad.net/~marutter/+archive/ubuntu/c2d4u,
  https://launchpad.net/~marutter/+archive/ubuntu/c2d4u3.5, or
  https://launchpad.net/~c2d4u.team/+archive/ubuntu/c2d4u4.0+ depending on
  which version of R you are using.

and has the (new !!) repo you are looking for:

  https://launchpad.net/~c2d4u.team/+archive/ubuntu/c2d4u4.0+

As Michael noted: new handle, and no longer under marutter.

And Michael is too modest. It works just fine. I have updated the Travis CI
support package (in GitHub repo eddelbuettel/r-travis) to support '3.5'
(old)
and '4.0' (new), and have already switched three different repos to use
it. For example RcppArmadillo now does a 'matrix' over 3.5 and 4.0, and
installs quite a few packages, including reticulate, from these repos. Works
like a charm [1] -- and I need to blog about the updated r-travis.

Sp big thanks to the ever-tireless Michael. Focal for R 4.0 is already at
3614 packages.

Hi Michael and Dirk!

Thanks to both of you for the answer (and sorry if I missed that in the
instructions)! Thanks Michael for all the good work for that ppa!!
