If you've read my earlier post, I was using Ubuntu, at that time, and I thought that was how you identify which distro is running in your system but using
lsb_release -a is not always going to work as some distributions may not have it installed.
Try the following command to identify the distribution you are running in your system:
And you'll get the following output:
NAME="XXXX" ID="XXXX" DISTRIB_ID="XXXX" PRETTY_NAME="XXXX"
Hope this helps you out!
