Method for modifying sources. list source of ubuntu 18.04 as Ali or Tsinghua image

1. Backup source list

Ubuntu default configuration of the source is not a domestic server, downloading and updating software are relatively slow, this article introduces how to set the source list, select a faster source to save download time.

#  Backing up the source list first 
sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

2. Open the sources. list file to modify

Choose the appropriate source, replace the contents of the original file, and save the edited file. Take Alibaba Cloud Update Server as an example (from the actual test results analysis, I think Alibaba Cloud is faster than Netease and Sohu's servers):

sudo vim /etc/apt/sources.list

3. Alibaba Cloud Image Source-Tsinghua Image Source

Note that depending on the specific version of Ubuntu used, replace trusty in the text with the string of the corresponding version below:

版本	版本号	代号
Lucid(10.04)	10.04	lucid
Precise(12.04): precise	12.04	precise
Trusty(14.04): trusty	14.04	trusty
Utopic(14.10): utopic	14.10	utopic
Ubuntu 16.04 TLS： xenial	16.04	xenial
Ubuntu 18.04 TLS： bionic	18.04	bionic
