Apologies for the delayed reply. This looks like a transient failure in image enumeration by jclouds.

If this is still an issue, please report the versions of pallet, pallet-jclouds and jclouds that you are using.

i'm seeing this error too : afaics the instance is created correctly though, so it doesn't seem to be critical

here are my jar versions : https://www.refheap.com/20567

i tried upgrading jclouds to 1.6.0, but there are some API changes and it failed, so i couldn't tell if the problem is sorted in later versions of jclouds

[hugoduncan]

Could it be happening on nodes where the ami they were started with has been removed from AWS?

[trampoline]

no : i got the error with two amis, one from the pallet first-steps guide, us-east-1/ami-3c994355, and the second alestic's latest ubuntu in ireland : eu-west-1/ami-a0dd3dd7 : both AMIs are still there

other things i thought of :

• i started using IAM keys, so i tried using the main account keys too : made no difference
• US vs EU : made no difference

i was out of ideas and time after that
