Unable to update Amazon Linux instance via yum

Question

I have an instance running Amazon Linux v2 (2017.12).  
  
If I try to update via yum, I get the following-

```
Could not retrieve mirrorlist http://amazonlinux.us-east-2.amazonaws.com/2017.12/core/$pointrelease/x86_64/mirror.list error was
14: HTTP Error 403 - Forbidden
```

The instance can access other hosts via http.   
  
If I try something as simple as
 `curl -I 'http://amazonlinux.us-east-2.amazonaws.com/'`
 I still get a _403 Forbidden_ response.  
  
I tried running _yum clean all_ and deleted everything in _/var/cache/yum_, but that had no effect.

Fixed it.  
  
Edit **/etc/yum.repos.d/amzn2-core.repo** .  
  
Replace   
  
_mirrorlist=http://amazonlinux.$awsregion.$awsdomain/$releasever/$product/$pointrelease/$basearch/mirror.list_  
  
with  
  
_mirrorlist=http://amazonlinux.$awsregion.$awsdomain/$releasever/$product/latest/$basearch/mirror.list_
