我遇到了 EC2 实例或 ubuntu 20.04 可能存在的问题。
当我跑步时sudo apt-get update
我最终得到:
Failed to fetch http://eu-west-
2.ec2.archive.ubuntu.com/ubuntu/dists/focal/InRelease Could not connect to eu-
west-2.ec2.archive.ubuntu.com:80 (34.241.117.189), connection timed out Could not
connect to eu-west-2.ec2.archive.ubuntu.com:80 (54.246.214.20), connection timed out
附加的安全组允许 http/s 流量。有人知道出了什么问题吗?
