It looks like Hashicorp have discontinued the atlas.hashicorp.com API endpoints used by the version of Vagrant in every Ubuntu release (in favour of vagrantcloud.com).
I've confirmed that this is fixed in the version of Vagrant in bionic- proposed: # vagrant box add 'ubuntu/trusty64' ==> box: Loading metadata for box 'ubuntu/trusty64' box: URL: https://vagrantcloud.com/ubuntu/trusty64 ==> box: Adding box 'ubuntu/trusty64' (v20180125.0.0) for provider: virtualbox box: Downloading: https://vagrantcloud.com/ubuntu/boxes/trusty64/versions/20180125.0.0/providers/virtualbox.box ... I'm looking in to this further. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1747426 Title: Error downloading box trusty64 metadata To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/1747426/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
