Public bug reported: Kubuntu 22.04, tigervnc-common 1.12.0+dfsg-4 amd64
What happens: When I start tigervncserver with option -SecurityTypes X509Plain it reports the following error: vncserver -geometry 1920x1080 -localhost no -autokill -SecurityTypes X509Plain You will require a certificate to use X509None, X509Vnc, or X509Plain. I will generate a self signed certificate for you in /home/mb/.vnc/demk-wks-400-SrvCert.pem. ----- Cannot write random bytes: 4057E14E287F0000:error:1200007A:random number generator:RAND_write_file:Not a regular file:../crypto/rand/randfile.c:190:Filename=/dev/urandom The openssl command /usr/bin/openssl req -newkey ec:/etc/tigervnc/openssl-ecparams.pem -x509 -days 2190 -nodes -config - -out /home/mb/.vnc/demk-wks-400-SrvCert.pem -keyout /home/mb/.vnc/demk-wks-400-SrvKey.pem failed: 256 which seems plausible since it can't write to /dev/urandmon. What should happen: vncserver creates a self signed certifiate and starts. Workaround (fix?) is to comment out the following line in /etc/tigervnc/openssl.cnf: #RANDFILE = /dev/urandom ** Affects: tigervnc (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1973292 Title: tigervnc server can't generate SSL certificate To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tigervnc/+bug/1973292/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
