Is it impossible to install R 4.0 on Ubuntu 18.04.4 LTS because r-base-core requires a libc6 version >= 2.29?

Question: Is your system otherwise current to 18.04? If so, the upgrade should just work. I wrote a blog post (prior to the release) about testing R 4.0.0 on 18.04 along with a video:

• blog post http://dirk.eddelbuettel.com/blog/2020/04/11#024_rocker_r_4_0_0_testing
• slides with links http://dirk.eddelbuettel.com/papers/r4_r400_binaries.pdf
• video showing the upgrade https://youtu.be/aa9lZJ7ZzKM

Two more recent (related) posts at http://dirk.eddelbuettel.com/blog/code/r4/ as well.

In short, on a system that is otherwise well (i.e. no other packages forced or conflicts or what have you), one just adds the new repo (shown in slides and video), updates the apt index and upgrades. I have done the same for my 19.10 Ubuntu system in another video.
