由于以下警告我可以/应该做什么吗?
W: Invalid 'Date' entry in Release file /var/lib/apt/lists/partial/_var_cuda-repo-8-0-local_Release
答案1
首先,您似乎正在运行 16.04 (Xenial),但仍配置了一些旧的 12.04 (Precise) 存储库。您确实应该删除它们。
对于另一个警告,文件可能以某种方式损坏了,无论是在您的计算机上还是在下载它的服务器上。您可以安全地删除它:
sudo rm /var/lib/apt/lists/partial/_var_cuda-repo-8-0-local_Release
甚至删除整个列表文件夹:
sudo rm -rf /var/lib/apt/lists
此后,您必须让 Ubuntu 再次下载/更新所有列表:
sudo apt update
这次警告应该会消失。如果没有,请等待一天或几天再重复,以防文件在服务器上损坏。
