我试图按照 lutris 的 apt 说明进行操作，但它们显然只适用于 debian，而我搞乱了 ubuntu 的 apt 密钥，所以其他任何东西都无法更新
我使用了以下命令
echo "deb [signed-by=/etc/apt/keyrings/lutris.gpg] https://download.opensuse.org/repositories/home:/strycore/Debian_12/ ./" | sudo tee /etc/apt/sources.list.d/lutris.list > /dev/null
echo "deb [signed-by=/etc/apt/keyrings/lutris.gpg] https://download.opensuse.org/repositories/home:/strycore/Debian_12/ ./" | sudo tee /etc/apt/sources.list.d/lutris.list > /dev/null
sudo apt update
我收到的错误是

我尝试了以下方法来修复它，但没有效果，所以我撤消了它
sudo cp -a /var/lib/apt/lists /tmp
sudo rm -r /var/lib/apt/lists/*
有没有办法为 apt 重新生成所需的 gpg 密钥？
编辑：回复@organic-marble如下：

我检查/dev/null了以下内容，但可能没有定论
sudo cat test.txt > /dev/null
