I am getting "" error when trying to install ambari-server in CentOS 7. Please find the screenshot attached for exact message I am getting. I have tried yum clean-all as well.
It looks like ambari repository is missing. Please download the repo and try installing again.
did you configure the reporsitories wget -n <repo url> -O /etc/yum.repos.d/ambari.repo
please see the sample doc :
and please run yum repolist
and check if you see ambari in the result
