Did you `make pdk-with-volare` as root?
What does `ls -ld /home/ratul619/IIT_study_VM/OpenLane/pdks/volare/sky130/current` return?

atul619@ratul619-VirtualBox:~/IIT_study_VM/OpenLane$ sudo make pdk-with-volare
[sudo] password for ratul619:
make: *** No rule to make target 'pdk-with-volare'.  Stop.

getting this

Looks like you created the original as root.
Try updating as root.  `sudo volare ls`
and then. `sudo volare enable &lt;commit&gt;` where `&lt;commit&gt;` is from the result of `volare ls`.

strangely if i do : sudo volare ls :

sudo: volare: command not found

You could try setting a new PDK_ROOT, and reinstalling there.
