Since yesterday I get the following error when attempting to apt-get update on Precise.
W: GPG error: https://apt.dockerproject.org ubuntu-precise Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F76221572C52609D
Does this require a fix by circleci? If so is it likely to happen now that Precise is EOL’d? (April 2017)
Ubuntu 12.04 or 14.04? (Your post title says Trusty but the description mentions Precise)
If you are using Ubuntu 12.04, yes it’s EOL’d and running apt-get update && apt-get upgrade will return more and more errors.
If you’re actually running the CircleCI Ubuntu 14.04 image, then let me know and we can investigate further.
Sorry, yes we’re having this problem with 12.04. As we’re going to have to migrate to 14.04 anyway I think we’re just going to work through the issues on that.
