Ubuntu Software Center doesn't have
configuration options for proxy server like Synaptic Package
Manager. In Synaptic, you can set server URL, port number, username,
and password. Such configuration makes Synaptic can enter directly to
proxy server with authentication so Synaptic can be connected via
that proxy server. But it is different with Ubuntu Software Center
(USC). USC hasn't graphical configuration like Synaptic so we must
set proxy server configuration in Ubuntu Global Network Proxy then
click Apply System Wide. But that way will never success because
Global Proxy Settings doesn't have place to set username and
password. Now, how to enter proxy server configuration completely
with right authentication so USC can connect to internet behind a
proxy server? This is the steps.
1. Open Terminal (Ctrl+Alt+T)
2. Change directory to
/etc/apt/apt.conf.d/ with command: cd /etc/apt/apt.conf.d/
3. Make a file there named 01proxy with
command: sudo gedit 01proxy.
4. Check the existence of 01proxy with
command: ls. If there, then a name 01proxy will appear in display. If
not, repeat step 3.
5. Edit content of 01proxy with
command: sudo gedit 01proxy.
6. Fill it with a row of this words:
Acquire::http::proxy
"http://username:password@proxyserver:port/";
with note:
username is your proxy username, password is your password,
proxyserver is yuor proxy URL or it's ip number, port is port number
to access the proxy (if you don't know, please confirm to your proxy
administrator). Example:
Acquire::http::proxy
"http://malsasa:traumalin89@proxyserver.server.net:443/";
7. Save (Ctrl+S).
Now you can try to install a program.
You can start with installing Stardict, a simple but great
dictionary.
