Solution to apt-key depreciation

Michael,

Sounds great!

If it's any help, I put my solution in a bash script:

#!/bin/bash
KEY=/usr/local/share/keyrings/marutter.key

if [ -f "$KEY" ]; then
  echo "$KEY already exists"
  sudo apt install -y r-base
else
  wget -q -O marutter.key
"https://keyserver.ubuntu.com/pks/lookup?op=get&search=0xe298a3a825c0d65dfd
57cbb651716619e084dab9" if ! file marutter.key | grep -q "PGP public key";
then
    echo "marutter.key does not appear to be a valid PGP key - aborting!"
    exit 1
  else
    sudo mkdir -p /usr/local/share/keyrings/
    sudo mv marutter.key /usr/local/share/keyrings/
    echo "deb [signed-by=/usr/local/share/keyrings/marutter.key]
https://cloud.r-project.org/bin/linux/ubuntu groovy-cran40/" | sudo tee -a
/etc/apt/sources.list fi
 sudo apt install -y r-base
fi

Nothing fancy by any means, but it works and could perhaps be useful.

Cheers,
Carl

Hi everyone,

Since apt-key will be deprecated in future releases of Debian
(https://manpages.debian.org/testing/apt/apt-key.8.en.html), I recently
got around to figuring out how to properly import Michael Rutter's key,
based on this answer over at askubuntu:
https://askubuntu.com/a/1307181.

Perhaps something along those lines should be added to the README at
https://cran.r-project.org/bin/linux/ubuntu/fullREADME.html?

Cheers,

Carl

Carl,

Thank you. I need to read these posts over to see if the instructions

can be condensed, but this is very helpful.
