Finally, I used Linux, used vmWare to install virtual machine under Windows, and hung Ubuntu 14.04. I felt very unaccustomed and difficult to serve.

Moreover, we have encountered many objective difficulties. We have spent a lot of time in the past two days. Basically is to go to work here to get online to configure proxy. Windows, in the IE connection configuration, other browsers can be used. With Ubuntu, it’s not that simple. Of course, in hindsight, it seems not very complicated, is not used to.

1. Ensure that two VM services, VMware NAT Service and VMware DHCP Service, are enabled. I shut them down because of a system optimization software, and ubuntu was unable to connect to the Internet

\

2, Go to Ubuntu System Settings, NetWork, then set agent, Apply (be sure to press Apply)

\

3. If the agent needs to specify a username and password, this step is required. And make sure you do 2 before you do this step.

Open the terminal and type sudo gedit /etc/environment

The system prompts you to enter the super administrator password. Note that under Linux, the password entry is not displayed, but it is.

Open the environment configuration file and enter the agent with the account and password. Such as

http_proxy=”http://account:password@proxyhost:port”

https_proxy=”https://account:password@proxyhost:port”\

…

After Step 2 is complete, the system will overwrite the proxy information, but there is no account information, only the proxy server information. If we do step 3 first and then step 2, our work will be overwritten.

\

4, Set up the proxies for apt-get and Update Manager

Run sudo gedit /etc/apt/apt.conf

Then type:

Acquire::http::proxy “http://account:password@proxyhost:port”; Acquire::https::proxy “https://account:password@proxyhost:port”; Acquire::ftp::proxy “ftp://account:password@proxyhost:port””; Acquire::socks::proxy “socks://account:password@proxyhost:port”; \

In this way, the software center, installation, update software can be smoothly connected. It’s important to keep your network open, otherwise installation, update failures, and error messages can drive you crazy.

However, these Settings don’t seem to work entirely with the browser, which asks for a password every time it opens.

\

In Linux, Firefox can set its own proxy. But Not Chromium from Google. It can use the system’s proxy, but it doesn’t work in Chromium without proxy Settings. The solution is to install the extension SwitchySharp in Chromium. The way to do that is to go to Chromium Settings, extension, SwitchySharp, find it, install it, set it, get it done. \
