Error during update 'Unable to connect to 192.168.43.1:8000'

Question

When I tried to update my Ubuntu through the update manager I received an error about some unknown resource. so i tried doing it from the terminal with

sudo apt-get update

but all I got is:

0% [Connecting to 192.168.43.1

repeating itself... and when I press Enter it shows:

W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/precise-security/universe/i18n/Translation-en  Unable to connect to 192.168.43.1:8000:

E: Some index files failed to download. They have been ignored, or old ones used instead.

How can I get this to work?

Answer 1

It looks like apt is configured to use a proxy since 192.168.*.* is a private IP range.

Use the next command to list all files in /etc/apt that contains 192.168.43.1:

grep -rlF 192.168.43.1 /etc/apt

It possibly prints /etc/apt/apt.conf. Open that file. Find a line that contains the proxy configuration and remove it:

Acquire::http::Proxy "http://192.168.43.1:8000/";

Save it and try updating again:

sudo apt-get update
