wget: command not found

Error can like like this
wget: command not found
Or
-bash: wget: command not found

This error occurs if wget is not installed on your server.
Might be you have a VPS server.

That means you don't have wget installed
Try this command
yum install wget

Now try wget command to download the package from server.
Hope this will work now.
