Hello, I have a squid proxy on the server and I can not get updates or install programs. It always fails when I try.

Code:
W: Imposible obtener http://security.kali.org/kali-security/dists/kali/updates/non-free/i18n/Translation-en  
No puedo iniciar la conexión a 3128:80 (0.0.12.56). - connect (22: Argumento inválido)

This happens if I click in one of the failed tries:

Code:
The requested URL /kali-security/dists/kali/updates/main/source/Sources was not found on this server.
