为有关源的“签名者”选项设置的值存在冲突

Question

我使用以下链接在 Ubuntu 22.04 上安装 Docker Engine https://docs.docker.com/engine/install/ubuntu/，一切正常，直到我到达sudo apt-get update，它给了我以下错误：

E: Conflicting values set for option Signed-By regarding source https://download.docker.com/linux/ubuntu/ jammy: /etc/apt/keyrings/docker.gpg != 
E: The list of sources could not be read.

我必须编辑该文件的权限：

E: Conflicting values set for option Signed-By regarding source https://download.docker.com/linux/ubuntu/ jammy: /etc/apt/keyrings/docker.gpg != 
E: The list of sources could not be read.

但还是发现错误，怎么办？

我试图删除 keyrings 目录，

sudo rm -r ./keyrings

并且仍然发现 sudo apt update 错误：

sudo apt update
E: Conflicting values set for option Signed-By regarding source https://download.docker.com/linux/ubuntu/ jammy: /etc/apt/keyrings/docker.gpg != 
E: The list of sources could not be read.

的输出ls -l /etc/apt/sources.list.d

Answer 1

重要提示：这个答案没有解决如何安装 docker。相反，它确实解决了如何避免命令给出的错误：sudo apt-get update添加 docker 存储库时：

E: Conflicting values set for option Signed-By regarding source https://download.docker.com/linux/ubuntu/ jammy: /etc/apt/keyrings/docker.gpg != 
E: The list of sources could not be read.

解决方案

您必须删除以下文件：

E: Conflicting values set for option Signed-By regarding source https://download.docker.com/linux/ubuntu/ jammy: /etc/apt/keyrings/docker.gpg != 
E: The list of sources could not be read.

如果有人不断收到相同的错误，那么应该删除以下文件：

sudo rm /etc/apt/keyrings/docker.gpg
sudo rm /etc/apt/sources.list.d/docker.list
