SSL_CERT_FILE not set
I am using Prusaslicer 2.9.4 on Kubuntu 24.04 Linux installed from flatpak. I get a dialog box when starting saying:
"Prusaslicer detected system SSL certificate store in: /etc/pki/tls/certs/ca-bundle.crt
To specify the system certificate store manually, please set the SSL_CERT_FILE environment variable to the correct CA bundle and restart the application."
I didn't have that directory so I sudo-created it and put a copy of ca-bundle.crt in there. Still no good. I used export to create the environment variable (export -p showed no variable). Still no good. The symptom I get in the application is that I can't use the network to send the gcode to the printer. I have to program the USB stick manually. The printer is 2 meters away and it's too hard to go that far! X-D
