salt-cloud salt master on GCE unable to import cloud gce

[Bramh Gupta]

Hello,

I am facing this issue while using a instance on GCE as the salt master. I have followed the instructions on the saltstack web site and have ensured all the prerequisites.

[root@saltmaster1 bramhg]# salt-cloud --list-locations gce

[INFO    ] salt-cloud starting

Hi,

The trace goes back to the Crypto package it seems - if that's installed (check with pip), check your public / private keys are correct and with correct permissions...

I could try this later myself and see what's happening.. What version are you running? Maybe paste the /etc/salt/cloud* files (without passwords etc please) ?

Alex,

Thanks for both the notes. It works now. I basically made sure that I am using the latest version of the PyCrypto per your instructions.

Thanks
