On my work network any apt-get (or aptitude) commands take a very long time, it's look's like admins blocked some port for it (for unknown reason). For example sudo apt-get update take like 2 days and all I get - a very long list of responses like Get: 36 http://security.ubuntu.com precise-security/universe amd64 Packages [11.6 kB] Get: 37 http://security.ubuntu.com precise-security/universe amd64 Packages [11.6 kB] Get: 38 http://security.ubuntu.com precise-security/universe amd64 Packages [11.6 kB] Get: 39 http://security.ubuntu.com precise-security/universe amd64 Packages [11.6 kB] Get: 40 http://security.ubuntu.com precise-security/universe amd64 Packages [11.6 kB] Same situation then I try to download software Get:1 http://archive.ubuntu.com/ubuntu/ precise/main dash i386 0.5.7-2ubuntu2 [85.8 kB] Get:2 http://archive.ubuntu.com/ubuntu/ precise/main dash i386 0.5.7-2ubuntu2 [85.8 kB] Get:3 http://archive.ubuntu.com/ubuntu/ precise/main dash i386 0.5.7-2ubuntu2 [85.8 kB] Get:4 http://archive.ubuntu.com/ubuntu/ precise/main dash i386 0.5.7-2ubuntu2 [85.8 kB] Get:5 http://archive.ubuntu.com/ubuntu/ precise/main dash i386 0.5.7-2ubuntu2 [85.8 kB] Is there something I can do to change port for apt-get or something else
