Re: trouble forcing apt-get into using local mirror
To answer my own question, it seems apt-get secretly prefers
sites which are authenticated, even when disabling authentication
as a commandline option..
I came across this as a 'bug' report which apparently hasn't been put through into
testing/stable yet. I would call it a bug since it is undocumented and in
my case unwanted behaviour when I supply no authentication to apt-get.
The solution is therefore to sign your own Release files.
1) gpg --gen-key (no passwd because apt-move has a batch to sign)
2) gpg --export -a PUBKEY | apt-key add -
3) add the key in apt-move.conf
