如何手动删除/删除添加的存储库？
请帮帮我：我手动添加了这个存储库，我不能删除它们
echo 'deb http://download.opensuse.org/repositories/home:/Horst3180/Debian_8.0/ /' > /etc/apt/sources.list.d/vertex-theme.list wget http://download.opensuse.org/repositories/home:Horst3180/Debian_8.0/Release.key 我尝试使用apt-key list删除apt-key list ，然后使用id删除，它成功删除了密钥，但是当我使用apt update我得到了这个输出：
W: GPG error: http://download.opensuse.org/repositories/home:/Horst3180/Debian_8.0 Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 5A7D1D38BEB6D886 E: The repository 'http://download.opensuse.org/repositories/home:/Horst3180/Debian_8.0 Release' 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.
我只是希望能够像apt update全新的OS安装一样运行apt update
只需删除创建的.list文件：
sudo rm /etc/apt/sources.list.d/vertex-theme.list sudo rm /etc/apt/sources.list.d/vertex-theme.list.save
在运行和更新之后，甚至可能是dist升级：
sudo apt update sudo apt dist-upgrade
由于您已经删除了密钥，因此您无需执行任何操作。
