没有按照LTS 版本 会遇到下面问题:
参考:https://zhuanlan.zhihu.com/p/691625646
Ubuntu 22.04代号为:jammy
Ubuntu 20.04代号为:focal
Ubuntu 19.04代号为:disco
Ubuntu 18.04代号为:bionic
Ubuntu 17.04代号为:zesty
Ubuntu 16.04代号为:xenial
查询 LTS 版本:
root@user-virtual-machine:~# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.4 LTS
Release: 22.04
Codename: jammy
root@user-virtual-machine:~#
修改sources.list文件
sudo gedit /etc/apt/sources.list
在Ubuntu 22.04中使用国内源可以提高软件包下载和更新的速度。以下是如何设置国内源的步骤:
备份原有的sources.list文件:
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
编辑sources.list文件:
sudo nano /etc/apt/sources.list
替换文件内容为国内源。以阿里云源为例,你可以将文件内容替换为以下内容:
deb http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse
保存并关闭文件。
更新软件源:
sudo apt update
升级所有安装的包:
sudo apt upgrade
