使用apt-get安裝時，會很慢，更換了國內(nèi)的源后，就可以解決這個問題了。

1. 備份sources.list文件

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

2. 打開sources.list文件

sudo gedit /etc/apt/sources.list

3. 刪除原內(nèi)容，添加下列內(nèi)容

#清華源

#阿里云源
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

這兩個源都可以用，我都試過，感覺阿里云源速度更快。

4. 更新

保存sources.list文件后需要更新apt-get。

sudo apt-get update

更新完成后就可以正常使用了。
