Ran the sudo command to extract the image manually then hit this, is this a new bug? This is all happening in a VM btw, not that it should make a difference:

^vmbuilder VM.

[Blake Rouse (blake-rouse)]

You are getting all these errors because of a bad or missing sudoers file. Same reason you for bug 1588868.

This means your sudoers file is incorrect for your installation of MAAS. Check the contents of:

/etc/sudoers.d/99-maas

Is this a fresh install or upgrade?

Is this in a container or on a host?

[mahmoh (mahmoh)]

Hi Blake,

There were two sudoers files and they both had what looked like complete entries, attached.

[mahmoh (mahmoh)]

We installed b5 on metal and it appears to be working fine, this problem is very reproducible using this script which relies on vmbuilder:

https://github.com/jmcdice/ubuntu-os-cloud

[Blake Rouse (blake-rouse)]

I would say then vmbuilder is doing something wierd. The user should not be "maas" for the installing user. "maas" should be reserved for MAAS. As sudoers will then override the "maas" users to be incorrect.

[mahmoh (mahmoh)]

@Blake, the user was joey and not maas. vmbuilder may be doing some odd things but maas should still work in the VM I'd argue no matter what and this is a great way to automate a maas install. The question is who's going to dig into the problem to see what's actually happening? That git repo has all the code and can easily reproduce the problem, maybe after 2.0 is released?

[Mike Pontillo (mpontillo)]

For what it's worth, I have my own scripts which deploy MAAS onto a VM based on a cloud image, and don't see this issue there.
