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

.

[#4]

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.

@Prashant Chaudhuri

The path "/tmp/ambari.repo" was example path. The correct path should be :

# cat /etc/yum.repos.d/ambari.repo 

.

[#7]

@Prashant Chaudhuri

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

[#8]

Thanks for your response Geoffrey.

cat /etc/yum.repos.d/ambari.repo

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.

@Prashant Chaudhuri

Can you confirm your ain't behind a proxy?

Just click this link to validate http://amibehindaproxy.com/

[#10]

No. The link confirms "No Proxy server detected".

Also re-checked my connection and found it's ok; but still the same result.
