Ubuntu版本：18.04 Apt版本：1.6.13
我尝试安装不同的 cuda 工具包，但这样做可能会不可避免地破坏 apt。但我认为问题与 cuda 无关，问题出在 apt 身上。
如果我运行sudo apt-get install *anything*（或 apt remove 或 apt purge），我会收到错误：
Reading package lists... Done Building dependency tree Reading state information... Done cuda is already the newest version (11.2.2-1). You might want to run 'apt --fix-broken install' to correct these. The following packages have unmet dependencies. cuda-drivers-460 : Depends: libnvidia-common-460 (>= 460.32.03) but it is not going to be installed libnvidia-gl-460 : Depends: libnvidia-common-460 but it is not going to be installed E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
所以我尝试sudo apt --fix-broken install：
Get:1 file:/var/cuda-repo-ubuntu1804-11-2-local libnvidia-common-460 460.32.03-0ubuntu1 [10.2 kB] Err:1 file:/var/cuda-repo-ubuntu1804-11-2-local libnvidia-common-460 460.32.03-0ubuntu1 File not found - /var/cuda-repo-ubuntu1804-11-2-local/./libnvidia-common-460_460.32.03-0ubuntu1_all.deb (2: No such file or directory) E: Failed to fetch file:/var/cuda-repo-ubuntu1804-11-2-local/./libnvidia-common-460_460.32.03-0ubuntu1_all.deb File not found - /var/cuda-repo-ubuntu1804-11-2-local/./libnvidia-common-460_460.32.03-0ubuntu1_all.deb (2: No such file or directory) E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
确实/var/cuda-repo-ubuntu1804-11-2-local不存在，更不用说其中的文件了。
运行sudo apt-get update收益：
E: The repository 'file:/var/cuda-repo-10-1-local-10.1.105-418.39 Release' no longer has a Release file. 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.

这可能又是由于没有/var/cuda-repo-ubuntu1804-11-2-local（或/var/cuda-repo-10-1-local-10.1.105-418.39）
遵循https://forums.linuxmint.com/viewtopic.php?t=281922
我也尝试过：
sudo su for FILE in $(dpkg-divert --list | grep nvidia-440 | awk '{print $3}'); do dpkg-divert --remove $FILE; done exit
但输入行开头for FILE...没有任何作用（nvidia-440用 450 或 460 替换也没有作用）
我正在使用 apt 版本 1.6.13，我尝试通过运行重新安装sudo dpkg -i apt_1.6.13_amd64.deb（从http://archive.ubuntu.com/ubuntu/pool/main/a/apt/apt_1.6.13_amd64.deb
）但运行上述任何程序时我仍然会遇到同样的错误
任何建议都将不胜感激 - 我真的想避免重新安装 ubuntu。
答案1
这更像是对 @ubfan1 的回复，但问题是我无法重新启动/删除系统上任何残留的 cuda。答案在如何在 Ubuntu 中安装 NVIDIA 和 CUDA 驱动程序？
提供了魔力：sudo rm /etc/apt/sources.list.d/cuda*
然后允许我运行更新，然后修复损坏的安装
答案2
我发现这sudo rm /etc/apt/sources.list.d/cuda-ubuntu2004-11-7-local.list已经解决了sudo apt update噪音问题（同时没有像 w1nter 的回答中那样删除其他 cuda* 文件）。以下是抄录：

在咨询了 w1nter 的回答后，我sudo apt update使用以下命令删除了错误：
