原因
今天给一台VPS重新安装系统，选择了最新的Debian13.2。在我安装Docker的过程中，出现了如下问题：
Get:15 http://deb.debian.org/debian trixie/main amd64 slirp4netns amd64 1.2.1-1.1 [39.3 kB]
Err:16 https://download.docker.com/linux/debian trixie/stable amd64 containerd.io amd64 2.2.1-1~debian.13~trixie

Error: Failed to fetch https://download.docker.com/linux/debian/dists/trixie/pool/stable/amd64/containerd.io_2.2.1-1%7edebian.13%7etrixie_amd64.deb 404 Not Found [IP: 3.169.231.6 443]
Error: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?可以看到是containerd.io_2.2.1-1~debian.13~trixie_amd64.deb这个包没找到。然后我就去docker官网查找这个包，发现最新的包是containerd.io_2.2.0-2~debian.13~trixie_amd64.deb 。应该是Metadata更新了最新的版本号，而Binary没跟上。
修复
既然没有containerd.io_2.2.1-1~debian.13~trixie_amd64.deb，那就安装官网最新版的containerd.io_2.2.0-2~debian.13~trixie_amd64.deb。
执行如下命令，查看仓库中的containerd.io的包
apt-cache madison containerd.io输出如下：
containerd.io | 2.2.1-1~debian.13~trixie | https://download.docker.com/linux/debian trixie/stable amd64 Packages
containerd.io | 2.2.0-2~debian.13~trixie | https://download.docker.com/linux/debian trixie/stable amd64 Packages

containerd.io | 1.7.28-0~debian.13~trixie | https://download.docker.com/linux/debian trixie/stable amd64 Packages
containerd.io | 1.7.27-1 | https://download.docker.com/linux/debian trixie/stable amd64 Packages由于第一个包并不存在，所以安装第二个（2.2.0-2）即可。
sudo apt-get install containerd.io=2.2.0-2~debian.13~trixie安装完成后，再执行安装docker的命令
sudo apt install docker-ce docker-ce-cli docker-buildx-plugin docker-compose-plugin查看docker是否安装成功
