Comment 4 for bug 1923673

Ahh, good point -- I had naively assumed it was an arch all package but you're absolutely right it's arm{hf,64} (and besides, it'd be good practice to use a .get there anyway).

On the distUpgrade, should all references be replaced with "do-release-upgrade"? I'm particularly thinking of things like the config.txt backup, currently being named config.txt.distUpgrade (which apes what happens to the apt sources.list). Or should I just be replacing distUpgrade references in the comments?
