I am trying to install openpdk and after providing 61GB space to ubuntu in VM I am getting error of no space.

So how much space do I need to install open pdk ?

If you can, you should use `volare` to pull pre-made PDKs. It saves the hassle of building yourself.

<@U02UAUGSQ22> Sir now when I am opening ubuntu in VM I am getting this error (I guess its because there is less space left) so do I need to install ubuntu again ?

Yes, no need to provide more drive space, see

During install, open_pdks creates additional data, so it needs quite a bit of space, much of it is deleted later.

Sir now when I restarted the machine I am not able to open it 
So I need to re install it ?

Not sure, I usually use Docker, not VirtualBox. 

yes you have to reinstall it , initially i had provided 50 Gb ... faced same error ... then provided 150Gb ... installed quite well , ,,, it was around 77 Gb

Ok sir 
So if I re install Ubuntu in vm 
How much minimum space should I give ?

around 120 Gb ... including all other software you require for project

<@U02UAUGSQ22> Sir 
Can you please help me with
How to use `volare` ? And how unwanted files are deleted later ?

First, install it using `pip install volare`. Then, find out which remote PDK versions exist by doing `volare ls-remote --pdk sky130` or `volare ls-remote --pdk gf180mcu`.

The environment variable `PDK_ROOT` needs to point where you want to store your PDKs.

Then install the version you want with something like `volare enable 4cfc6af9ceba75a2f35c76f89ece76aa539f9a8d --pdk sky130`
