為什麼我無法執行“sudo apt-get update”？

我最近開始使用 linux mint。我正在嘗試在我的終端中執行以下命令 sudo apt-get update。但我總是得到這個輸出：

我該如何解決這個問題？

提前致謝

編輯cat /etc/apt/sources.list.d/additional-repositories.list：：

deb http://archive.canonical.com/ sarah partner
deb http://archive.canonical.com/ sarah partner

首先，請注意，它apt-get update仍然會酌情更新其索引，它只是抱怨它無法下載其某些儲存庫所需的資訊。

sarah是 Mint 代號，而不是 Ubuntu 代號，因此嘗試使用sarahCanonical 託管的儲存庫是沒有意義的；您可以安全地刪除其他儲存庫：

sudo rm /etc/apt/sources.list.d/additional-repositories.list

這將修復您看到的錯誤。

沒有莎拉版本的 ubuntu。僅在使用 linuxming 發行版時才使用 linuxmint 儲存庫。
