![sudo apt update 总是发现更新问题](https://linux22.com/image/1017280/sudo%20apt%20update%20%E6%80%BB%E6%98%AF%E5%8F%91%E7%8E%B0%E6%9B%B4%E6%96%B0%E9%97%AE%E9%A2%98.png)
由于我无法在互联网上找到答案,因此我将在这里尝试:当我运行命令时
sudo apt update
它总是更新同样的东西。输出如下:
sudo apt update

所以如果我再次竞选
sudo apt update
那么输出是相等的。有人能帮我吗,或者这是正常的吗?
答案1
这完全正常。apt update 所做的就是从 Ubuntu 存储库更新软件包列表。如果没有更新,则它不必更新任何内容。
