Yesterday, I completely abandoned the operating system of Windows 7. 7, which was half a year old and switched to Ubuntu. After ubuntu is installed, apt software packages and system update are inevitable, and the download speed is slow, so the source is modified, the following is a source with the fastest speed I feel. The download speed is mainly kb/s ~ Kb/s. I feel very good. I keep a file and it may be used later.

Copy the above Code to/etc/apt/sources. list to overwrite and save it. Tip: you only need one of the fastest sources to update. You do not need to store all sources on the Internet.
Then update the source:
sudo apt-get update
Now, apt software in Linux is faster!
