卸载docker时的apt update报错

遇到了两个问题

服务器：腾讯云Ubuntu 22.04

起因是安装docker失败，想删干净，参考大佬的文章完全删除docker，使用apt upadte的时候出现报错

1. Ubuntu: apt-get update: Target Packages is configured multiple times.

使用脚本安装docker

curl -s https://get.docker.com/ | sh

或者添加 Docker 的官方 GPG 密钥

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

上述两者情况会出现类似如下报错

W: Target Packages (stable/binary-amd64/Packages) is configured multiple times in /etc/apt/sources.list.d/archive_uri-https_download_docker_com_linux_ubuntu-jammy.list:1 and /etc/apt/sources.list.d/docker.list:1

方法一：

cd /etc/apt/sources.list.d 会发现有个docker.list，直接删掉即可
参考文章：国外文章

方法二：

1. sudo apt install python3-apt
2. 访问github链接，下载pyz文件到Ubuntu中,不能下载的话，我将文件放在了置顶。
   
3. chmod a+x aptsources-cleanup.pyz
4. sudo ./aptsources-cleanup.pyz

2. W:https://linux.teamviewer.com/deb/dists/stable/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

输入下面两条命令即可快速解决：

cd /etc/apt
sudo cp trusted.gpg trusted.gpg.d

参考优快云专家文章之后，知道这个trusted.gpg是安装docker时执行下面命令生成的密钥，索性直接将trusted.gpg删除

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
