So I have just looked in to this, and I can't reproduce it. I did the following:
$ vagrant --version Vagrant 1.8.1 $ vagrant init ubuntu/xenial64 <snip> $ vagrant up <snip> $ vagrant ssh -- sudo grep hosts /etc/nsswitch.conf hosts: files dns (I've also done some interactive sudo'ing in there, and I haven't seen any issues) I've done this with both the default hostname, and setting a hostname in the Vagrantfile. If someone can provide full reproduction steps, I'd be more than happy to reopen this and address it, but as of now I can't find a bug to fix. :) ** Changed in: cloud-images Status: Confirmed => Incomplete ** Changed in: livecd-rootfs (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1561250 Title: Xenial vagrant image is missing its hostname in /etc/hosts To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/1561250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
