If you're like me and paid for Cyberghost VPN as it was one of the few solutions that offerred a linux app, only to have these ghosts evaporate along with your hopes and dreams that it would be a no-effort install, welcome.
I foolishly assumed that a "Linux client" would include all flavors, yet was sorely cast into the ditches and subnets of injustice.
Fear not, I have a chunky and clumsy solution for you (If you use Parrot and paid for this service.)
Just run the install file and it should be straight gravy. It took a few times to catch a working VPN the first few times I turned it on but was OK after that.
For y'all new jacks:
sudo chmod +x install.sh
sudo bash ./install.sh
