Comment 2 for bug 1551584

We had unavailable mirrors:

./puppet/bootstrap_admin_node.log:Could not retrieve mirrorlist http://mirror.fuel-infra.org/mos-repos/centos/mos9.0-centos7-fuel/mos-mirrors-os.txt error was
./puppet/bootstrap_admin_node.log:14: curl#6 - "Could not resolve host: mirror.fuel-infra.org; Unknown error"

Also we had no fuel-nailgun installed on the master node.
Marking as invalid. Please reopen the bug if will be reproduced.
