我可以在 Ubuntu 20.04 中删除 /var 中没有验证签名（NO_PUBKEY 错误）的目录吗？

当我执行sudo apt-get update命令时，我得到以下终端输出：

我对 的错误/警告感到担忧/var/cuda-repo-ubuntu2004-11-3-local/Release.gpg。我已经检查过ls /var/，有一个较新的 cuda-repo，我刚刚手动安装，但是，我不确定是否删除较旧的 repo。因此，我的问题是：

  1. 应从中删除过期的、未经验证的目录/var，或者
  2. 有没有其他“干净”的方法来处理这个问题，或者
  3. 尽管有警告，该 repo 是否仍然相关并且应该被保留？
  4. 其他...

消除此警告的最佳做法是什么？

我感谢您的帮助！

干杯，

路易斯

mashuptwice 已经在评论中指出，删除错误的存储库是解决方案。正确执行此操作的解释如下这里.使用像add-apt-repository和这样的命令行工具。ppa-purge
