Shulou(Shulou.com)06/01 Report--

This article mainly introduces how to update the source of Ubuntu12.04, the article introduces in great detail, has a certain reference value, interested friends must read it!

It is too slow to use foreign sources, and it will be much faster to change them to domestic sources. Here is to share the modification method for you, friends who need it can refer to it.

1.sudo gedit / etc/apt/sources.list

Edit your source list, delete all the original contents or make a backup

Sudo cp / etc/apt/sources.list / etc/apt/sources.list.backup (backup current source list)

Add the source that works best for you in the list below (be careful not to add it all), select the one that works best for you, copy it to your list, and then save the list.

2.sudo apt-get update updates source list information

You can check the error message while running "sudo apt-get update", delete the unreachable sources and rerun "sudo apt-get update".

3.sudo apt-get upgrade can also be upgraded or upgraded with the update manager that comes with ubuntu.

Educational network source

If you are a college student, you can use the campus network / education network, that is, use the resources of the education network, especially those that support ipv6, then the update speed is calculated by megabytes.

4. Update the source (type the following command in the terminal)

Sudo apt-get update

After installing Ubuntu18.04, it is too slow to use a foreign source, and it will be much faster to change it to a domestic source.

Modify the Ali source to the default source of Ubuntu 18.04

Backup / etc/apt/sources.list

# backup

Cp / etc/apt/sources.list / etc/apt/sources.list.bak

Add the following entry before the / etc/apt/sources.list file

# add Ali source

Deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

Deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

Deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

Deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

Deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

Deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

Deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

Deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

Deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

Deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

Finally, execute the following command to update the source

# # Update

Sudo apt-get update

Sudo apt-get upgrade

Several other domestic sources are as follows:
