Setting up vpn on Kali using OpenVpn

SInce I dont have a customo router i want to set up my vpn before I do anything using Kali. Ive been in touch with Pure VPN and have tried getting their help, no luck. im using instructions from https://support.purevpn.com/linux-openvpn-command When I get to Step 5, run command: cd “open”… I get, No such directory. but if you go to my home folder you will clearly see the folder named (“open”)… If i skip that and go to step 6 run command" sudo cp ca.crt TCP/* UDP/* Wdc.key /etc/openvpn/… i get “no such file or directory” fpr all for files…

Why do you need a VPN on Kali?

We cover setting up VPNs in volume 3.

couldnt hurt? alright and thank you.
