Setting up Proxy settings on peppermint 5

[archietaz]

Hi.  I am a n00b in the world of Linux and I am unsure how to setup a a auto proxy configuration setting.  I am trying to setting up laptops for my school
a) My computer is a Lenovo s10-3
b) We use a hidden network
c) the proxy configuration file that is located at ,http://proxy.nycboe.org/proxy.pac.  The problem is I don't know where/how to input in this.

I appreciate any help you could provide

Is this just for chromium, or does it need to be systemwide ?

Can you try this...

First install libpacparser1:

Code: [Select]

sudo apt-get install libpacparser1

Then with Chromium closed, run:

Code: [Select]

chromium-browser --proxy-pac-url=http://proxy.nycboe.org/proxy.pac

does the chromium instance that just opened work  ?

Wow... that worked out well. =)

Thanks for your help and sorry for the delay in reply.

Is there a way to set the proxy settings system wide?

This should apply that proxy.pac every time you open Chromium.....

Open a terminal and run:

Code: [Select]

sudo gedit /etc/chromium-browser/default

and make it read:-

Code: [Select]

# Default settings for chromium-browser. This file is sourced by /bin/sh from
# /usr/bin/chromium-browser

# Options to pass to chromium-browser
CHROMIUM_FLAGS="--proxy-pac-url=http://proxy.nycboe.org/proxy.pac"

SAVE the file.

Now close ALL running instances of Chromium .. then reopen Chromium (normally from the menu) to test.

Okay.....
a) I typed in what you suggested and Chrominium goes on line like a champion
b) I am not sure the setting are global though.  I am having a problem updating my software using the software updater and I am wondering if it is related.
c) Here is one of the error messages:

FAILED TO DOWNLOAD REPOSITORY INFORMATION
check your internet connection
E:GPG error:http://extras.ubuntu.com trusty
InRelease: Clearsigned file isn't valid, got
'NODATA' (does the network require authentication?)

Try this .. run:

Code: [Select]

sudo gedit /etc/apt/apt.conf.d/proxy

when a BLANK file opens, add a single line that reads:-

Code: [Select]

Acquire::http::Proxy "DIRECT";

SAVE the file and exit gedit.

Now test with:

Code: [Select]

sudo apt-get update

and look out for 404 errors


If it doesn't work, remove that file with:

Code: [Select]

cd /etc/apt/apt.conf.d

then

Code: [Select]

sudo rm -v proxy
