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! -- Steve Gutreuter [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
