Proxy does not work using sudo

14.04 proxy

Solution 1

In case anybody wonders:

The issue here, is that when sudoing, a newenvironment is loaded, meaning that http_proxy is no longer set.

To resolve this issue you can add Defaults env_keep += "http_proxy https_proxy" to your /etc/sudoers file in order to keep those variables when switching to the secure path.

Reference: https://help.ubuntu.com/community/EnvironmentVariables

Solution 2

Open /etc/apt/apt.conf file in Terminal and set your proxy setting as following:

Acquire::http::proxy "http://user:pass@host:port/";
Acquire::https::proxy "https://user:pass@host:port/";
Acquire::ftp::proxy "ftp://user:pass@host:port/";
Acquire::socks::proxy "socks://user:pass@host:port/";

Replace user with your username, pass with your password, host with proxy-webaddress and port with a portnumber.

I set the proxy using system setting -> Network -> Network Proxy. I then clicked on "Apply system wide", put my password, and nothing else.

Instead using sudo:
```
michele@rserver-VirtualBox:~$ sudo wget http://bbc.co.uk

I am on 14.04 and I didn't have this issue before upgrading from 12.04 yesterday. Please tell me what other info you need.

  Why do you want to use sudo here while it works well without that?

  Check your /etc/apt/apt.conf file and see if your proxy setting is also appear there.

  that is simply a reproducible example... my server runs application on behalf of different users, so I need the proxy to work for all users.

  To workaround, use it like this: sudo env HTTP_PROXY=http://proxy.example.com:port wget http://bbc.co.uk.

  Did you try @the_Seppi's suggestion? When you run sudo, environment is restricted.

  @Letizia yes, it did not work

  Did you try to configure and uncomment http_proxy in /etc/wgetrc file?

  You need to make some changes in your /etc/sudoers file. Take a look at this: ubuntuforums.org/showthread.php?t=2199416.

did you restart the system
Michele over 9 years

No, I thought it was a Windows thing... :-) I'll try now
Michele over 9 years

Nada... still the same. I just read that sudo does a reset of the environment variables and things like http_proxy don't get used

@Michele Sorry but I don't have any idea check here askubuntu.com/questions/175172/… and here askubuntu.com/questions/15719/… and also here askubuntu.com/questions/82880/…

Just a note: this would still requires the respective environment variables to be set inside the profile of the user, who belongs to the sudoers. Add export http_proxy=... and export https_proxy=... to .bashrc or whatever your user's profile file is called. Also I recommend putting no_proxy, which is quite common for company networks, where internal network locations (e.g. intranet web portal) often not only do not require but will not work if going through proxy.
