Question

當我跑步時

$ sudo apt-get update

我明白了

sudo apt-get update

由於以下警告，我可以/應該做些什麼嗎？

Answer 1

首先，您似乎正在運行 16.04 (Xenial)，但仍然配置了一些舊的 12.04 (Precise) 儲存庫。你真的應該刪除它們。

對於另一個警告，文件可能以某種方式損壞，無論是在您的電腦上還是在下載該文件的伺服器上。您可以安全地刪除它：

sudo rm /var/lib/apt/lists/partial/_var_cuda-repo-8-0-local_Release

或甚至刪除整個清單資料夾：

sudo rm -rf /var/lib/apt/lists

之後，你必須讓 Ubuntu 再次下載/更新所有清單：

sudo apt update

這次警告應該消失了。如果沒有，請等待一天或幾天並重複，以防伺服器上的檔案可能損壞。
