Bizarre, can you post the content of

# cat /etc/resolv.conf 

The rerun the below

# yum clean all 
# yum clean metadata

Then

#  yum install -y ambari-server

Let me know

[#3]

# cat /etc/resolv.conf
; generated by /sbin/dhclient-script
search domain.name pc.com
nameserver 192.168.1.1

domain name above is dummy one and nameserver IP is actually that of my router. could that be a problem? But... I remember having worked in similar setup in past, though long back.

@Prashant Chaudhuri

Can you edit your resolv.conf and add the 2 names server before your router like this

nameserver 8.8.8.8 
nameserver 8.8.4.4 
nameserver 192.168.1.1

he rerun the below

# yum clean all 
# yum clean metadata

Then

#  yum install -y ambari-server

And revert

[#5]

changed resolv.conf and tried above commands. Still no success.

[#6]

@Prashant Chaudhuri

Can you add the below line in /etc/yum.conf

http_caching=packages

The re-run the previous commands

[#7]

Thanks. Done, but no success yet.

[#8 · Accepted solution]

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.

[#9]

+1 2.5.2.0 version has the problem. 2.5.1.0 version works fine.

[#10]

is there a solution to this issue?

[#11]

please correct the repo file path. 2.5.2.0 also works fine with corrected path. Observer ppc in the path correct it for ambari. Than you should be good. I have done this for RHEL 7.
