我最近在我的 PC 上安装了 Ubuntu Server 22.04，但每次我写入时sudo apt update，它总是说：
W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/jammy/InRelease Temporary failure resolving 'archive.ubuntu.com'
W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/jammy-updates/InRelease Temporary failure resolving 'archive.ubuntu.com'
W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/jammy-backports/InRelease Temporary failure resolving 'archive.ubuntu.com'
W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/jammy-security/InRelease Temporary failure resolving 'security.ubuntu.com'
W: Some index files failed to download. They have been ignored, or old ones used instead.
我也尝试使用多个本地镜像和主镜像。
对于如何解决这个问题，有任何的建议吗？

这是 /etc/apt/sources.list
