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
Thanks for the response. I actually have access to that url: http://amazonlinux.default.amazonaws.com/2/core/latest/x86_64/mirror.list, which returns a mirror.list with this url: https://cdn.amazonlinux.com/2/core/2.0/x86_64/073693aa0842a0f3e16526cb49af0137eeb4a56b5ff2be7040f1f066bf8b8069 which is the one I have no access to. (it returns 403) Take into account I'm running the VM, on-premise, not on AWS following the tutorial in the link I posted above. Is there a way I can have access to those repos from outside AWS?
I found a question with a similar situation to yours, but I can't seem to find a solution. https://stackoverflow.com/questions/58764259/amazon-linux-on-premise-yum-update-fails
I've tried searching, but there's not much information and I haven't been able to find a concrete solution.
