Ubuntu sudo apt get update 404 Not Found 问题

我正在使用 Ubuntu 20.04.3 LTS。两天来我一直遇到一个错误，即我无法更新或升级或在我的系统上执行软件包安装，因为出现以下错误：

我该如何解决这个问题？

答案1

您的大多数存储库和 PPAsources.list不再可用，并且会抛出错误。我建议恢复默认存储库。

  1. 首先，使用以下命令恢复默认存储库：

    mkdir ~/solution
cd ~/solution/

cat << EOF > ~/solution/sources.list
deb http://archive.ubuntu.com/ubuntu/ focal main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ focal main restricted universe multiverse

deb http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse

deb http://archive.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse

deb http://archive.ubuntu.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ focal-backports main restricted universe multiverse

deb http://archive.canonical.com/ubuntu focal partner
deb-src http://archive.canonical.com/ubuntu focal partner
EOF

sudo sed -i "s/focal/$(lsb_release -c -s)/" ~/solution/sources.list
sudo rm /etc/apt/sources.list
sudo cp ~/solution/sources.list /etc/apt/sources.list

  2. 删除系统中的所有 PPA：

    sudo mv /etc/apt/sources.list.d/* ~/solution

  3. 更新存储库：

    sudo apt update

可以了，好了！
