我打算在终端上运行这些命令
sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update
sudo apt upgrade
并出现这些错误
E: Failed to fetch
http://il.archive.ubuntu.com/ubuntu/dists/focal-updates/universe/cnf/Commands-amd64.xz Hash Sum mismatch
...
E: Some index files failed to download.
They have been ignored, or old ones used instead.
我尝试了这些建议来解决问题，但没有效果
sudo apt-get clean
sudo rm -r /var/lib/apt/lists/*
全部输出sudo apt update

我该如何解决这个问题？谢谢！
答案1
这似乎不是您添加的新 ppa 的错误：相反，这似乎是您使用的 ubuntu 存档中的一个错误。我无法重现它：您可以再试一次吗？您可能在存档正在更新时正在工作。
