Ubuntu – apt-get behind proxy on VirtualBox Ubuntu

The logging using the suggested solution showed lots of errors in dealing with filesystem, etc.. Installation hangs for very long periods of time and never finishes. I think the problems occur because ubiquity is trying to run as user. I am installing Linux Mint 16 Cinnamon edition (64 bit). The system previously had a Cent OpenStack system with LVM installed on it.

I found another approach that worked flawlessly. It requires you to elevate into root before you run ubiquity. But you must also provide the required proxy environment variables....

Boot the Mint CD to the trial desktop...

1. Set manual proxy in the system settings, set whatever proxy settings you need for your networking environment.

2. Start terminal.

3. Enter the command:

   sudo -E bash

4. Now you are in a root session with the environment inherited from the user session (-E option did this for you)

5. Now at the command prompt enter:

   ubiquity gtk_ui

Ubuiquity runs as root and the install went perfectly with no problems at all. Only took a couple of minutes to complete. !!

apt-get install

doesn't do any installation , the correct syntax is:

apt-get install package_name

But did you see the output of that program in terminal ?

And setting proxy in firefox won't affect a global proxy settings , you may need to refer to Network Manager in Ubuntu.

@update:

the whole progress will be involved , e.g when install mscorettf-installer with wget

%> cat /etc/apt/apt.conf.d/00proxy 
Acquire {
    Retries "0";
    HTTP {
        Proxy "http://221.176.168.178:80";
    };
};
