[R] Unable to add the CRAN apt repository

[Steve Gutreuter]

Thanks!  "jammy" made it work.  

For some reason,  lsb_release -cs is returning "victoria" rather than "jammy",
and

$> sudo apt update
Hit:1 http://archive.ubuntu.com/ubuntu jammy InRelease 
Ign:2 http://packages.linuxmint.com victoria InRelease 
Get:3 http://archive.ubuntu.com/ubuntu jammy-updates InRelease [119 kB]

kB]

A Mint problem?
