Ubuntu 24.04 bootstrap process doesn't disable the stock Ubuntu repos

[ppanon2022]

Older versions of Ubuntu have the repos defined in /etc/apt/sources.list but Ubuntu 2024.04 has them in /etc/apt/sources.list.d/ubuntu.sources. The bootstrap process doesn't seem to know to disable them in the new location, so they still show up on an apt update alongside the Uyuni channels.

We use a salt module to list the repositories and disable them. Could it be that salt does not work with the 'new' Deb822 format?

Hmm. so we need to wait until someone adds support for that 'new' format. I suppose the challenge is that it's more tricky to comment out multiple lines than a single one, because you need to figure out where to start and where to end. Actually, looks like you just need to modify (or insert if it doesn't exist) an "Enabled: no" line.
