@hassaniraj  Looks like the error reported in this thread could be due to the same reason mentioned on another thread of yours: https://community.cloudera.com/t5/Support-Questions/Hortonworks-sandbox-2-5-yum-update-not-working/m-p/278491 . It will be great to follow the same instructions mentioned on that thread to see if that fixes this issue. Specially  if you see some "dev2.hortonworks.com.s3.amazonaws.com" repos base URLs inside your "/etc/yum.repos.d" repos then please refer to the other thread and try to disable them and try again. You should set the "enabled=0" (this will disable the sandbox.repo) which has issue. As that is just development repo and might not be available always. https://community.cloudera.com/t5/Support-Questions/yum-install-error-please-help-me-out/m-p/203121 After removing the problematic repos try to perform a clean at yum level and then try again: # yum clean all # yum install python-pip . ...

@hassaniraj  1. Please try restarting the VM once. 2. Inside the sandbox do SSH login and then try to see if you are able to make the following curl call .. this is just to verify the repo accessibility. If the following URL does not work then please share the HTTP Header section output of the following curl commands here so that we can verify if there are some special headers like Network proxy ..etc. # curl -iLvk <a href="http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.21/repos/centos6/repodata/repomd.xml" target="_blank">http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.21/repos/centos6/repodata/repomd.xml</a> AND   # curl -iLvk <a href="http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.21/repos/centos6/repodata/7fcacadb44b1a860fb704795c187f549103e855a0a93ed31293a0b270a9022b4-primary.sqlite.bz2" target="_blank">http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.21/repos/centos6/repodata/7fcacadb44b1a860fb704795c187f549103e855a0a93ed31293a0b270a9022b4-primary.sqlite.bz2</a>   3. If above works fine then we will have to look from the YUM side. Please try to perform the yum cache cleanup and then retry:   # yum clean all # yum update   4. It will be also good to verify if the "/etc/yum.repos.d/" directory has any problematic repo. Can you please list them?   # ls -lart /etc/yum.repos.d/   For temporarily you can move some of the repo files from "/etc/yum.repos.d/" file to outside and then retry... this will help in isolating if there are any corrupted repo issue. 5. Recently have you made any changes to the "/etc/yum.conf" file like enabling/disabling any proxy setting ..? # cat /etc/yum.conf   Also if you see some "dev2.hortonworks.com.s3.amazonaws.com" repos URLs inside your "/etc/yum.repos.d" repos then please refer to the other thread and try to disable them and try again: https://community.cloudera.com/t5/Support-Questions/yum-install-error-please-help-me-out/m-p/203121 Example:   # cat /etc/yum.repos.d/sandbox.repo [sandbox] baseurl=<a href="http://dev2.hortonworks.com.s3.amazonaws.com/repo/dev/master/utils/" target="_blank">http://dev2.hortonworks.com.s3.amazonaws.com/repo/dev/master/utils/</a> name=Sandbox repository (tutorials) gpgcheck=0 enabled=0       . .
