Hi Enrique,

Thank you for reporting this bug! Can you please run:

sudo ua collect-logs

That will help us diagnose this issue.

Excellent, thank you!

It looks like we're getting an error when using ubuntu-distro-info: "ubuntu-distro-info: unrecognized option `--supported-esm'".

And from the attached Dependencies.txt I see you're on distro-info version 0.18~ubuntu16.04.1 from xenial-backports. That has a higher version than ubuntu-advantage-tools Depends requirement (>= 0.14ubuntu0.2) but apparently doesn't support the feature we need and that is present in version 0.14ubuntu0.2.

Are you able to downgrade distro-info to version 0.14ubuntu0.2? Or do you have other packages that require version 0.18~ubuntu16.04.1?

apt install distro-info=0.14ubuntu0.2

apt should prompt if it wants to downgrade/remove other packages and you can cancel if that's unacceptable.

If that doesn't work or if it requires downgrading/removing other packages that you need to keep, then I can supply you a short script to manually detach, while we work on an actual fix to this bug.

The actual bugfix will likely be that ubuntu-advantage-tools should process the distro-info-data directly without relying on the ubuntu-distro-info tool

Hi @teward, I see [1] in [2] as a triple self rejection.
But nothing left in [3] unapproved.

I might have lost the updates on this.
On Sept 27th in #ubuntu-devel it felt like we agreed this should be uploaded to -backports.
I tested it and then didn't keep track.
Rechecking the bug made me find it rejected.

Do you know what happened that changed this approach?

Yeah I got swamped and inundated with other work tasks. It's on my radar to reupload with the new version by EOD today and then auto-approve into Backports because I have an ACK from the other backporters members on this one.

I self-rejected my upload because of the incorrect version string of ~bpo18.04.1 - it should be 16.04.1 for Xenial. I have not been able to get back to this yet.

I've uploaded and approved the backport with the correct version number, that should land in Backports soon.
