linux - sudo apt update 被 ubuntu 中的 403 错误中断

Question

我正在尝试更新我的存储库，但我不断收到来自 docker 的错误，我不知道如何修复它。
错误:

Failed to fetch https://download.docker.com/linux/ubuntu/dists/focal/InRelease  
403  Forbidden [IP: 2600:9000:2251:e800:3:db06:4200:93a1 443]
 E: The repository 'https://download.docker.com/linux/ubuntu focal InRelease' is not signed.
 N: Updating from such a repository can't be done securely, and is therefore disabled by default.
 N: See apt-secure(8) manpage for repository creation and user configuration details.

我假设我必须手动将 InRelease 文件添加到 docker，但我需要指导，因为我对 ubuntu 完全陌生。

您是否在 official docker installation 之后添加了官方 GPG key ？在ubuntu上？

sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates curl gnupg lsb-release

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

假设您在 x86_64/amd64 系统上，执行:

 echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

我建议您遵循该指南，而不是通过 apt 安装。
