[Regression Potentional]
This fix supports both pre juju beta7 which used 'lxd' as the cloud type and beta7 upwards which supports 'localhost' as cloud type. Regression should therefore be minimal since it was completely broken with the latest release of juju.

[Tero Saarni (tsaarni)]

Is there workaround for this until the fix ends up in xenial-updates?

[Stephen Mahood (s-mahood)]

Adding the PPA (https://launchpad.net/~conjure/+archive/ubuntu/ppa) and updating has fixed this issue for me

[Chris J Arges (arges)]

Hello Adam, or anyone else affected,

Accepted conjure-up into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/conjure-up/0.1.2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[BlueT - Matthew Lien - 練喆明 (bluet)]

I have the same issue.

Can confirm that the new version in Proposed repo fixed this.

[Launchpad Janitor (janitor)]

This bug was fixed in the package conjure-up - 0.1.2

---------------
conjure-up (0.1.2) xenial-proposed; urgency=medium

  * Fix 'creds' KeyError traceback on cloud selection (LP: #1586131)
  * Support Juju beta7
