Accessing Amazon Linux 2 yum repositories from an on-premises VM

0

I have successfully set up a Amazon Linux 2 VM on Virtualbox by following the guide: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/amazon-linux-2-virtual-machine.html. The problem comes when I try to update the system by running sudo yum update. It always fails with:

Loaded plugins: langpacks, priorities, update-motd
Could not retrieve mirrorlist http://amazonlinux.default.amazonaws.com/2/core/latest/x86_64/mirror.list error was
14: curl#6 - "Could not resolve host: amazonlinux.default.amazonaws.com"


 One of the configured repositories failed (Unknown),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Run the command with the repository temporarily disabled
            yum --disablerepo=<repoid> ...

     4. Disable the repository permanently, so yum won't use it by default. Yum
        will then just ignore the repository until you permanently enable it
        again or use --enablerepo for temporary usage:

            yum-config-manager --disable <repoid>
        or
            subscription-manager repos --disable=<repoid>

     5. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

Cannot find a valid baseurl for repo: amzn2-core/2/x86_64

Is there a way to solve this?

Thanks

Hello.

Judging from the error contents, it appears that the name "amazonlinux.default.amazonaws.com" cannot be resolved.
It may be a good idea to review the VM's network settings, etc.
