apt-get update did not run even after updating apt.conf file

[Gyanesh Kumar Mahana]

Generally I am a FEDORA user. I formatted my system and installed ubuntu yesterday.I could not update even after the correct network setting.My network connection is correct and I am able to browse through net.
I updated apt.conf for proxy settings
I updated the source.list file too
but bug remains same

I installed system twice and changed apt.conf :
"Acquire::http::username:<email address hidden>:80/"
as
"Acquire :: http :: username : gkm010mkg@<email address hidden>:80/"
then I realized the big bug............

my password contained @ symbol.and the SOFTWARE WRITTEN TO READ THE APT.CONF READS IT 'LEFT TO RIGHT'; AS MY PASSWD CONTAINED @ SYMBOL, IT TOOK '<email address hidden>' as the server address INSTEAD OF 'proxy.cse.iitb.ac.in',and obviously could not fetch it..!!
::::::::::::::::::::::::::::::::::::::::::REMEDY::::::::::::::::::::::::::::::::::::::::
THE SOFTWARE SHOULD BE RECODED AS READING APT.CONF FROM RIGHT TO LEFT FOR ROBUSTNESS.

The option is called: Acquire::http::Proxy, so your setting should be
Acquire::http::Proxy "username:<email address hidden>:80";

Host-specific settings would be Acquire::http::Proxy::<host> there <host> is the address of the sources.list entry (e.g. if you have to use a proxy only for certain parts of the web).

If you want to use a "special" character in username or password you have to encode it, so try to use "%40" instead of "@".
