22.04 Apt update failed to fetch

I recently installed Ubuntu Server 22.04 on my pc, but every time I wrote sudo apt update, it always kept saying:

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.

I tried using multiple local mirrors and the main one too.

Any suggestions on how to fix this?
