Paddy I’m not sure where you are currently on the source issue:
This is how I got it working:
sudo /usr/bin/wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/google.gpg >/dev/null
gpg: WARNING: unsafe permissions on homedir '/home/me/.gnupg'
Not the same error, after update:
Warning: https://dl.google.com/linux/chrome/deb/dists/stable/InRelease: The key(s) in the keyring /etc/apt/trusted.gpg.d/google.asc are ignored as the file is not readable by user executing gpgv.

This worked for me.
sudo apt modernize-sources
This is shown after:
The following files need modernizing:
- /etc/apt/sources.list
- /etc/apt/sources.list.d/google-chrome.list
Modernizing will replace .list files with the new .sources format,
add Signed-By values where they can be determined automatically,
and save the old files into .list.bak files.
This command supports the 'signed-by' and 'trusted' options. If you
have specified other options inside [] brackets, please transfer them
manually to the output files; see sources.list(5) for a mapping.
For a simulation, respond N in the following prompt.

Something like this:
sudo grep -r google /etc/apt | grep -v amd64
