Unable to update Ubuntu 10.04 using proxy connection – “No address associated with hostname”

June 14, 2010 by msverman

I decided to install Ubuntu 10.04 (Lucid Lynx) in PC today and the outlook looks good. I was very much surprised that “GIMP” was missing in this release and then I tried to update Lucid Lynx.

verman@verman-desktop:~$ sudo apt-get update
[sudo] password for verman:

Err http://security.ubuntu.com lucid-security Release.gpg
Something wicked happened resolving ‘security.ubuntu.com:http’ (-5 – No address associated with hostname)
Err http://security.ubuntu.com/ubuntu/ lucid-security/main Translation-en_IN
Something wicked happened resolving ‘security.ubuntu.com:http’ (-5 – No address associated with hostname)

W: Failed to fetch http://in.archive.ubuntu.com/ubuntu/dists/lucid-updates/multiverse/source/Sources.gz Something wicked happened resolving ‘in.archive.ubuntu.com:http’ (-5 – No address associated with hostname)

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

This Showed me a error “No address associated with hostname” in all the line.

Then I tried all the possibility to update Lucid Lynx.

I was using Proxy Internet connect and I didn’t touch any settings.

Proxy is working fine and able to browse all website in the Internet.

Then suspect it has nothing to do with proxy .

Even when i manually exported HTTP proxy: http://myname:mypassword@proxy Port: 8080 , apt-get update was not working.

After a long search using my friend google, I found that we had to acquire http proxy in apt.conf file

Then I just added a line in /etc/apt/apt.conf

Acquire::http::Proxy “http://myname:mypassword@proxy:8080″;

after that it worked charm!

verman@verman-desktop:~$ sudo apt-get update
[sudo] password for verman:
Hit http://in.archive.ubuntu.com lucid Release.gpg
Ign http://in.archive.ubuntu.com/ubuntu/ lucid/main Translation-en_IN

verman@verman-desktop:~$

Thanks to Google ……….

Now I will try installing “GIMP”

  Do you have a internet connection ?

  If you copy paste it won’t work,
  
  try to added a line by typing in /etc/apt/apt.conf
  
  Acquire::http::Proxy “http://myname:mypassword@proxy:8080″;

Hi guyz
I am new to ubuntu and this computer stuffs, sorry to ask that question which might seem stupid but please do i have to change the “myname” and “mypassword” ? to the name and password i use?
isn’t dangerous to put the password in the open like this?

Also help me how to find the “myname” ….
if in the console we have :
verman@verman-desktop:~$

thus the “myname” is verman???

Thanks for your explanation.

Then I just added a line in /etc/apt/apt.conf

Acquire::http::Proxy “http://myname:mypassword@proxy:8080″;

in addition to this i added in .bashrc
http_proxy=”http://…:port_number” and
ftp_proxy=”http://…:port_number”

then it started working.

To make sure the proxy is correct, i used the wget command and to make wget command to work, i added the proxy details to /etc/wgetrc and tried to get the google web page using wget http://www.google.com.

If you find /etc/apt/apt.conf doesn’t exist on 10.04 Ubuntu boxes, you can just create it.

You might want to also set an FTP and HTTPS proxy…

Acquire::http::proxy “http:///”;
Acquire::ftp::proxy “ftp:///”;
Acquire::https::proxy “https:///”;

you need not to do that thing manually you can do this that is you can configure your proxy using network proxy manager preinstalled in ubuntu.

This does not work in Ubuntu 11.04.
There seems to be nothing regarding a “Direct connection” (i.e. No Proxy) option. Shouldn’t this work without any proxy ?

I have just upgraded to ubuntu 11.10 and I have the same problem. I cannot use apt-get update, but everything else works such as wget and web browsing. But I cannot install any software because of this apt-get problem. When I opened /etc/apt/apt.conf it has only one line in it, which is

Acquire::http::proxy “http://127.0.0.1:9666/”;

I didn’t set a password and username and I am using ultrasurf. Anyone help me please?
