Ubuntu 22.10 Kinetic无法更新archive.ubuntu.com仓库的问题求助

你好，我今天遇到了Ubuntu更新的异常问题，昨天还能正常操作，今天执行更新命令就报错了。我运行的更新命令是：

sudo apt update

得到的错误输出如下：

我的网络是正常的，这台虚拟机部署在Proxmox上，昨天还能正常更新。当前的netplan配置（注：原配置里的dhcp4: no:( And m是输入失误，已修正）如下：

network:
  ethernets:
    ens18:
      dhcp4: no
      dhcp6: no
      addresses:
        - 192.168.122.205/24
      routes:
        - to: default
          via: 192.168.122.1
      nameservers:
        addresses: [8.8.8.8, 8.8.4.4]
  version: 2
  renderer: networkd

问题分析与解决方案 #

首先得明确：Ubuntu 22.10（Kinetic Kudu）是非长期支持（Non-LTS）版本，它的官方支持周期早在2023年7月20日就结束了。官方会停止对非LTS版本的软件更新支持，并且把对应仓库从archive.ubuntu.com迁移到旧版本归档仓库old-releases.ubuntu.com，这就是你遇到404错误的核心原因——原仓库地址已经没有Kinetic的相关文件了。

解决步骤如下：

1. 备份原有软件源配置
   先备份相关配置文件，防止操作失误导致问题：

   sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
   sudo cp -r /etc/apt/sources.list.d/ /etc/apt/sources.list.d.bak
   

2. 批量替换仓库地址
   使用sed命令把所有配置文件里的archive.ubuntu.com和security.ubuntu.com替换为归档仓库地址：

   sudo sed -i 's/archive.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
   sudo sed -i 's/security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
   sudo sed -i 's/archive.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list.d/*.list
   sudo sed -i 's/security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list.d/*.list
   

3. 重新执行更新
   现在再运行更新命令，应该就能正常获取软件包列表了：

   sudo apt update
   

4. （可选）升级到LTS版本
   如果你希望长期获得官方的安全更新和软件支持，建议升级到最新的LTS版本（比如Ubuntu 22.04 LTS或24.04 LTS），可以通过以下命令操作：

   sudo do-release-upgrade
   

   注意：升级前请务必备份重要数据，确保网络稳定。
