[R] Unable to add the CRAN apt repository

[Steve Gutreuter]

I just upgraded from Linux Mint 20 to 21 and am no longer able to add the CRAN
Ubuntu repository to my list of repositories.  I am getting:

$> sudo /usr/bin/add-apt-repository "deb
https://cloud.r-project.org/bin/linux/ubuntu $(lsb_release -cs)-cran40/"
$> sudo apt update
Hit:1 http://security.ubuntu.com/ubuntu jammy-security InRelease
Hit:2 http://archive.ubuntu.com/ubuntu jammy InRelease
Hit:3 http://archive.ubuntu.com/ubuntu jammy-updates InRelease
Hit:4 http://archive.ubuntu.com/ubuntu jammy-backports InRelease
Ign:5 http://packages.linuxmint.com victoria InRelease
Hit:6 http://packages.linuxmint.com victoria Release
Ign:8 https://cloud.r-project.org/bin/linux/ubuntu victoria-cran40/ InRelease
Err:9 https://cloud.r-project.org/bin/linux/ubuntu victoria-cran40/ Release
404 Not Found [IP: 108.139.15.91 443]
Reading package lists... Done
E: The repository 'https://cloud.r-project.org/bin/linux/ubuntu victoria-cran40/
Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore
disabled by default.

Any hints will be much appreciated!
