This environment is using juju 2.6-beta1, but this behavior is being seen in 2.4 and 2.5

Are you updating the series from a client or from the machine itself? The client is required to help manage the flow as the agent will go down and restart. I'm not sure it's viable to do it from the machine you're actually upgrading?

[Richard Harding (rharding)]

Actually, you've bypassed the upgrade series feature entirely from what I can see here.

Please see https://docs.jujucharms.com/2.5/en/upgrade-series and let me know if I'm misunderstanding your issue. Marking incomplete pending feedback.

This is quite different from the document we were using
https://docs.jujucharms.com/2.4/en/howto-updateseries , the user that
found this issue was following that howto.

I will try with the one you pointed out.

[Felipe Reyes (freyes)]

Once I used "juju update-series" before trying to use "juju ssh app/N -- sudo juju-updateseries ..." things worked.

So my question now is if it's possible to make the error message more informative, at least for 2.5 or 2.6
