Just as a test I have just renamed ubuntu.sources.curtin.old as ubuntu.sources.curtin.orig and no warning or error appeared when running sudo apt update.
Whether or not this is a complete fix remains to be seen but it's a start.
Can I assume that with that new name the file really is being parsed as it should be?
