1. 備份源列表
Ubuntu缺省的配置的源并不是國內的服務器骇吭，下載更新軟件都比較慢怖糊，本文介紹如何設置源列表，選擇比較快的源以節(jié)省下載時間悬钳。
# 首先備份源列表
sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup
2. 打開sources.list文件修改
選擇合適的源塞蹭，替換原文件的內容，保存編輯好的文件, 以阿里云更新服務器為例（從實際測試上結果分析门坷，個人認為阿里云比網(wǎng)易和搜狐的服務器要快）：
sudo vim /etc/apt/sources.list
3. 阿里云鏡像源-清華鏡像源
注意根據(jù)具體使用的Ubuntu的版本不同宣鄙，將文本中trusty替換為下面對應版本的字符串:
| 版本 | 版本號 | 代號 |
|---|---|---|
| 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 |

4. 刷新列表绸吸，一定要執(zhí)行刷新
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential
