Plesk 17.8.11 on Debian 9.13

I am trying to update both of these to Plesk 18 / Debian 10 respectively and thought I might simply follow these instructions to update Debian:

https://support.plesk.com/hc/en-us/articles/12377714344983

Then these instructions to update Plesk:

Upgrading Plesk for Linux Using Installer Console

If you want to be able to upgrade to a Plesk version other than the latest stable release, you can upgrade using the ...

docs.plesk.com

However while following the instructions in the first link:

11. Make installer to create Plesk sources list for Debian 10:

# plesk installer --override-os-version 10.0 --check-updates --skip-cleanup --source http://autoinstall-archives.plesk.com

exit status 1

I proceeded through steps 12 and 13 anyway, but apt update freezes at 0% [Working] every time I run it:

# apt update

Am I not doing this correctly or missing something?
