Hi mothivenkatesh,
To switch your site to Linux, go to your site management panel, and try the following:
1) Click the + next to the hosting
2) Clicked on options, then the customize tab
3) Select the drop down menu under “Plan” and scroll up to select Linux
According to GoDaddy, it can take up to 48 hours for the changes to apply, but your site will be completely transferred, and you will then be able to use Jetpack.
If you do not feel comfortable making the change by yourself, do not hesitate to contact GoDaddy directly to let them know about the issue.
