Issue body
I have apt-cacher-ng installed on my laptop which may be a variable involved in this?
Whenever I do a "snapcraft cleanbuild" it sets up lxd and then does an apt update and then tries to get the necessary packages needed for my snap and 500 errors when getting the debs. Every time. Not a transient issue, been like it for days.
