2024年Ubuntu18.04执行do-release-upgrade报错的解决方案
背景
公司用的信服云，公共镜像中最新的Ubuntu镜像是
18.04.2，使用22.04的iso安装会卡在安装界面无法安装，尝试多种方法最终是使用18.04的公共镜像创建一台云主机，升级至22.04后，作为模版主机，以后有需要创建云主机的时候使用克隆的方式创建新主机。碰到问题时网上搜了不少解决方法，都无法解决，最后通过"狸猫换太子"的方式把它解决了。
本文仅记录下解决方法，略过那些费时的试错过程了。
报错情况
bash
root@traffic-entrance:~# do-release-upgrade
Checking for a new Ubuntu release
Failed to connect to https://changelogs.ubuntu.com/meta-release-lts. Check your Internet connection or proxy settings
There is no development version of an LTS available.
To upgrade to the latest non-LTS develoment release
set Prompt=normal in /etc/update-manager/release-upgrades.解决方法
先升级可用的软件包
bash
# 先升级所有可以升级的包，升级完后需要重启
# 如果不升级的话，后面会提示 : `Please install all available updates for your release before upgrading.`
apt update && apt upgrade -y && reboot执行 do-release-upgrade
方法一：直接执行 github 上写好的脚本
bash
curl https://raw.githubusercontent.com/taills/tools/master/ubuntu-do-release-upgrade.sh |bash方法二：手动执行
建议保存为一个 sh 文件来执行，因为升级到20.04后，还需要再升级到22.04，也会报一样的错哈。
bash
#!/bin/bash
# 创建临时文件夹，用于存放升级信息
mkdir /tmp/temp_web
# 以下升级信息可以用浏览器访问 https://changelogs.ubuntu.com/ 获取，在ubuntu18里面curl或wget是获取不到的，想了解原因的可自行搜索。
# 写入升级信息，可从 https://changelogs.ubuntu.com/meta-release 获取
