Ubuntu-配置apt源

Ubuntu-配置apt源

1.阿里源

1.备份源

root@ubuntu1804-1:~# sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

2.替换源内容
vim /etc/apt/sources.list

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

3.更新列表

sudo apt-get update
执行，此时可能会报错GPG error: http://dl.google.com/linux/chrome/deb stable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 78BD65473CB3BD13，这是公钥的问题，执行sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 报错说明的公钥即可添加，此时再次执行sudo apt-get update即可更新软件列表。

4.更新软件包（配置源，可不安装）
执行命令sudo apt-get upgrade进行已安装的软件更新，注意该命令是更新所有已安装软件，时间较长，谨慎使用。

2.清华源

1.备份源

root@ubuntu1804-1:~# cp /etc/apt/sources.list /etc/apt/sources.list.bak
