Update from 3.4.0.22 to 3.4.0.24 urges user to remove system packages

Oh, well. That would be nice instead of this confusing message!
@Jolla : just the latest confused (and multiple topic creating) user.

Not sure whether @olf 's sfos-upgrade supports this. But if not, would it be worth a feature request? @olf :slight_smile:

another request @Jolla, @vige, @jovirkku
Could we somehow make @abranson 's post sticky or copy it into a new topic?
