'ERROR: ssl certificate doesn't exist: /home/rsvay/snap/barrier-kvm/2/.local/share/barrier/SSL/Barrier.pem

I am a frequent user of Barrier-kvm. I recently upgraded my server to Ubuntu 20.04 and started getting error "ERROR: ssl certificate doesn't exist: /home/rsvay/snap/barrier-kvm/2/.local/share/barrier/SSL/Barrier.pem". I was unable to get any answer using key word "Barrier-kvm" and it took me hours to solve the problem. So i want to share my solution.

Copy the path to SSL directory which you can find in your error. "ERROR: ssl certificate doesn't exist: /home/rsvay/snap/barrier-kvm/2/.local/share/barrier/SSL/Barrier.pem "
In this case : "/home/rsvay/snap/barrier-kvm/2/.local/share/barrier/SSL/"

Then run the following commands:

cd  "path to your SSL"
mkdir -p Fingerprints
openssl req -x509 -nodes -days 365 -subj /CN=barrier -newkey rsa:4096 -keyout Barrier.pem -out Barrier.pem
openssl x509 -fingerprint -sha1 -noout -in Barrier.pem > Fingerprints/Local.txt
sed -e "s/.*=//" -i Fingerprints/Local.txt

Rsvay's solution worked for me after I corrected the file name. capitalize the B: change 'barrier.pem' to 'Barrier.pem'

$ mv ~/.local/share/barrier/SSL/barrier.pem ~/.local/share/barrier/SSL/Barrier.pem

It worked for me in Ubuntu 20.04. However the barrier.pem file generated after running the code is case sensitive, I had to change to Barrier.pem and it runs perfectly.

You can disable the SSL Fingerprint from the barrier setting in both server and client. Then it will work smoothly.
