When running the update command for CoreOS I get an update failed error. According to the documentation this means that there are no updates found. This shouldn't be the case as the version I'm running is CoreOS stable (647.2.0).
update_engine_client -update
$> cat /etc/os-release
NAME=CoreOS
ID=coreos
VERSION=647.2.0
VERSION_ID=647.2.0
BUILD_ID=
PRETTY_NAME="CoreOS 647.2.0"
ANSI_COLOR="1;32"
HOME_URL="https://coreos.com/"
BUG_REPORT_URL="https://github.com/coreos/bugs/issues"
$> cat /etc/coreos/update.conf
GROUP=stable
SERVER=https://customer.update.core-os.net/v1/update/
How can I trigger the update proces?
