apt-get install dá 404 não encontrado, mas o URL funciona

Question

Estou tentando configurar um repositório apt .

Este repositório está realmente substituindo um que já existe e está funcionando bem. Não consigo instalar um pacote deste repositório.

No meu /etc/apt/sources.list , eu tenho a linha:

deb http://mirror.cs50.net/appliance50/2014/debs/dists/trusty/main/binary-i386 /

Um apt-get update passa perfeitamente bem. Mas então algo como apt-get install appliance50 (um pacote nesse repositório) me dá:

Err http://mirror.cs50.net/appliance50/2014/debs/dists/trusty/main/binary-i386/  appliance50 2014-0
  404  Not Found
E: Failed to fetch http://mirror.cs50.net/appliance50/2014/debs/dists/trusty/main/binary-i386/./appliance50_2014-0_i386.deb  404  Not Found

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

Mas, em seguida, copiar esse URL em um navegador faz o download do arquivo muito bem! Existe algum passo fundamental que estou perdendo? Isso tem que fazer alguma coisa com o fato de que esse servidor está redirecionando a solicitação para o S3?

Editar:

Aqui está a saída de "sudo apt-get -o Debug :: Acquire :: Http = true install appliance50", de acordo com o comentário:

É um erro no apt-get , que não está enviando os cabeçalhos GET corretos, então o servidor responde com o 404.

Por exemplo, telnet para o servidor mirror.cs50.net na porta 80 (HTTP) e insira o seguinte (emulando uma solicitação do apt-get):

GET /appliance50/2014/debs/dists/trusty/main/binary-i386/./appliance50_2014-0_i386.deb HTTP/1.1
User-Agent: Debian APT-HTTP/1.3 (1.0.1ubuntu2)
Host: mirror.cs50.net
Accept: */*

Então você verá o seguinte:

telnet mirror.cs50.net 80
Trying 54.84.6.206...
Connected to mirror.cs50.net.
Escape character is '^]'.

Se deixarmos de fora o ponto ( /./ ) na solicitação GET, a solicitação responderá com um redirecionamento, ou seja, 302, o que está correto.

Eu verifiquei isso com outros espelhos e eles relatam o mesmo:

Você deve incluir no seu relatório de bug que o apt-get deve remover os cabeçalhos get do ponto-n-slash.
