How to resolve permission denied error at Preparing Servers when attempting to install Packstack
Hi, I'm attempting to install Packstack on Centos 7, but it keeps throwing an error at the step 'Preparing Servers'. I've added my public rsa key to the server, but it's still an issue. I've installed the OpenStack Stein version. Any help would be appreciated. Thanks!
[cotadmin@controller ~]$ sudo packstack --answer-file /root/answers.txt --timeout=1500 | tee packstack-output.txt

What does your answer file look like, and which server is 192.168.5.30? Is it an all-in-one installation?
Do you also get the error when installing with default answers, i.e.
sudo packstack --allinone?This key korey@DESKTOP-TB3RRQG doesn't look right.
Perhaps this is your scenario: https://ask.openstack.org/en/question.... Set
PermitRootLogin noin the sshd_config file.Hi,It's not an all-in-one installation. I installed packstack with
sudo yum install -y openstack-packstack. I'm able to ssh into the server with that public key. the PermitRootLogin was commented out. I set it to yes and then no but still same issue. Thanks for pointing me to that scenario tho.According to https://www.rdoproject.org/install/ad...:
Did that happen? I wonder if the non-root user's key is the culprit. The above-mentioned page doesn't mention keys.
Hi, no I wasn't prompted for any passwords just yet. It's possible the key is the issue. I initially thought the issue is because i'm using Stein Openstack instead of the latest. Maybe I could try wiping Packstack and reinstalling again.. Thanks for your help.
