Just to filter possibility of any issues with the setup of that particular instance of Centos, I tried installing on another instance as well, but it still fails.
Also to nullify any connection issues, I tried curl on the GPG key from ambari.repo - it works fine and downloads the key.
Surprise.. Surprise.. I just tried Ambari 2.0.0 installation and it works fine.. So it may be problem with Ambari 2.5.2.0 (In fact entire 2.x I think) repository.

Can you please check if your "/etc/yum.repos.d/ambari.repo" file has "enabled=1" value as following:
wget -nv http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.5.2.0/ambari.repo -O /etc/yum.repos.d/ambari.repo # cat /tmp/ambari.repo #VERSION_NUMBER=2.5.2.0-298 [ambari-2.5.2.0] name=ambari Version - ambari-2.5.2.0 baseurl=http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.5.2.0 gpgcheck=1 gpgkey=http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.5.2.0/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins enabled=1 priority=1
.
Also please do a yum clean all and then try again, and please check the repo access from your host.
# yum clean all
.

Additionally in order to isolate any proxy issue please check if you are able to access the "repomd.xml" file from the ambari repo?
# wget -nv http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.5.2.0/repodata/repomd.xml
.
Also check the "/etc/yum.conf" if any proxy is defined there? Or if you need any?
# grep 'proxy' /etc/yum.conf
.

wget command works fine and downloads repomd.xml.
grep for 'proxy' returns nothing.
Actually I'm working from home, so usual corporate network restrictions do not apply in my case.

Thanks for your quick response.
* I checked "/etc/yum.repos.d/ambari.repo" and it does have enabled flag = 1. However I do not have any ambari.repo file in /tmp.
* I did "yum clean all", checked ambari appears in repolist and ran "yum install ambari-server", but still the same failure.

The path "/tmp/ambari.repo" was example path. The correct path should be :
# cat /etc/yum.repos.d/ambari.repo

Can you paste the contents of your. The /tmp/ambari.repo was just a typo error it should have been cat /etc/yum.repos.d/ambari.repo
# cat /etc/yum.repos.d/ambari.repo # cat /etc/yum.repos.d/hdp.repo
Clean all the cached files from any enabled repository at once
yum clean all
Check the repolist
yum repolist
The retry the
yum install -y ambari-server

Thanks for your response Geoffrey.
cat /etc/yum.repos.d/ambari.repo #VERSION_NUMBER=2.5.2.0-298 [ambari-2.5.2.0] name=ambari Version - ambari-2.5.2.0 baseurl=http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.5.2.0 gpgcheck=1 gpgkey=http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.5.2.0/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins enabled=1 priority=1
I do not have HDP repo downloaded, hence I simply get following for hdp repository:
cat: /etc/yum.repos.d/hdp.repo: No such file or directory
After doing yum clean all and checking yum repolist (output of it below); I'm still getting message "No package ambari-server available.

No. The link confirms "No Proxy server detected".
Also re-checked my connection and found it's ok; but still the same result.
