Error: "Cannot retrieve repository metadata (repomd.xml) for repository: HDP-2.3. Please verify its path and try again"

[#1]

when I try to use yum to update or install some packages, I get this error. .

"http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.3.2.0/repodata/repomd.xml: [Errno 14] PYCURL ERROR 7 - "couldn't connect to host" Trying other mirror. Error: Cannot retrieve repository metadata (repomd.xml) for repository: HDP-2.3. Please verify its path and try again"

I am working on HDP 2.3.4 Sandbox deployed on a CentOS 6 server which is behind the proxy. The server has internet access. I can ping google.com , for example.

the contents of /etc/yum.repos.d looks like this:

Any workaround regarding this issue would be highly appreciated!

@Kibrom Gebrehiwot

[root@sandbox yum.repos.d]# cat /etc/resolv.conf

nameserver 8.8.8.8

[root@sandbox yum.repos.d]#

What do you have in that file?

@Neeraj Sabharwal

/etc/resolve.conf contains the IP address for the Global DNS server and nameservers of my LAN.

@Kibrom Gebrehiwot Can you run this ? wget https://community.hortonworks.com/storage/temp/1943-repofiles.png

Output looks like this:

@Kibrom Gebrehiwot So...You don't have access to internet as you can see that your connection is refused. Can you take a backup of /etc/resolve.conf and add that entry which I shared?

Are you on corporate vpn? Firewall blocking outbound traffic in your laptop?

[#8]

@Neeraj Sabharwal nameserver 8.8.8.8 already exists in /etc/resolv.conf

The sandbox is installed on Centos 6.7 and I am remotely accessing it with PuTTY.

I can access the Web UIs from the browser. There is corporate firewall too.

[#9]

@Kibrom Gebrehiwot send me your file and I will try to reproduce

Please see those redhat links

Can you remove other entries from that file ?

Are you on vpn?

Do you have firewall on ?

Is iptable off in sandbox?

[#10]

@Neeraj Sabharwal

This is content of /etc/resolv.conf

nameserver 8.8.8.8

nameserver 10.0.225.44

• I am not on VPN
• firewall is on
• iptables is ON in Sandbox

[#11]

@Kibrom Gebrehiwot

Please turn off iptables 🙂
