I tried to login into old EC2 AWS ubuntu server and doing apt-get update. I got issue with so many “IGN” where no hit. I thought this issue because source.list. Apparently this issue because now ubuntu have different path for software update for old ubuntu version.
Please use this to replace your “us-west-2.ec2.archive.ubuntu.com” into “old-releases.ubuntu.com”.
