Build and use--ubuntu Update settings for Linux development environment

when the Ubuntu operating system is released, it is only equipped with basic system software and application software to reduce the volume of the operating system. Most of the software that we need to use in our development needs to be updated from the Web.

If Ubuntu doesn't have a network, it can be said to be unable. Let's teach you how to use the Internet and Local area network for updates.

Internet Update (external network update)

A virtual machine or a physical machine that can be connected to the Internet, which can update the software directly from the Internet.

Ubuntu default update source speed is not fast, we can change to 163 or Sohu provided update source.

We can do this through the graphical interface:

We can also set through the command in the terminal:

1, first backup Ubuntu12.04 source list

sudo cp/etc/apt/sources.list/etc/apt/sources.list.backup (back up the current source list)

2. Modify the update source

sudo gedit/etc/apt/sources.list(open Ubuntu 12.04 Source list file)

3, the "2, modify the update source " Inside the content to replace the following content

163 Source:

When the source file is changed, the local update source is selected when the system is updated.

4, update the source (in the terminal to knock the following command)

LAN update

in the company, generally do not choose the Internet update, because the company's limited network resources , if the same time a lot of people are updating, it is likely to lead to the company's network paralysis . Therefore, in the company, usually set up a server, this server to all the software is updated well (even if not all updates, the server is also convenient to update regularly, after all, only one machine occupies network resources), and then, the company's employees update the software through this server, this way update is LAN Update-Simple, rough.

The Local Area network update setting method is the same as the Internet update setting (set by command).

Not the same place is 3, the "2, modify the update source " inside the content replaced with the following content ", the modified content is not the same, the IP address for the company server IP:

After setting up the local Area network update source, we can update the system and application using the graphical interface or the character interface.

Graphical interface:

Character interface (recommended):
sudo apt-get update //Gets a list of the latest packages that must be executed after the update source has been set up. Equivalent to " check " in graphical interface operation.
sudo apt-get install XXX//installing XXX software from the source
sudo apt-get remove XXX//delete package
sudo apt-get download xxx//Download the XXX Deb package from the source
sudo apt-get source xxx//Download the source code of XXX from sources package
sudo apt-get upgrade//update system files

The character interface updates the application instance:
Install the "Open in terminal" tool by right-clicking on the terminal and knocking at the following command:

sudo apt-get update//First-time update, first knock this, and then do not

sudo apt-get install nautilus-open-terminal

After you log off the machine, on the desktop, right-click the mouse to see "Open in Terminal."
