HI,
Can you provide more information such as how you installed elasticsearch, what os, what version of elasticsearch/xpack?
I have installed elasticsearch using the tar.gz package. and i am using ubuntu 14.04 , Elasticsearch-5.1 and Xpack 5.1
Hey,
what is the exact path of the syskeygen binary? You can find out using the command which. The path mentioned in the error /etc/elasticsearch/x-pack/system_key - was that created by yourself? Or are you using the debian package or may have a leftover of that installation?

Hi Alex
path of syskeygen is elasticsearch-5.1.1/bin/syskeygen
/etc/elasticsearch/x-pack/system_key this is not created by me and not created also.
yes i used debian package for installation
These statements seem to conflict a bit. Do you still have the installation from the debian package? If not, can you remove or rename the /etc/default/elasticsearch file (assuming that it exists).
i deleted /etc/elasticsearch folder . and then generated syskeygen . now its working . Thank you for the help
