Recently upgraded from Ubuntu 20.04 to 22.04. I am trying to install RealVNC Server on an Ubuntu 22.04 LTS desktop. I downloaded the Debx64 file from here: https://www.realvnc.com/en/connect/download/vnc/linux/. Then ran the install command in the terminal and received the following error:
N: Download is performed unsandboxed as root as file '/home/user/Downloads/VNC-Server-6.11.0-Linux-x64.deb' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)
This is a non-successful install i.e. RealVNCServer does not run after receiving this error.
The full terminal output is:
$ sudo apt install ./VNC-Server-6.11.0-Linux-x64.deb

I then clicked on the VNCServer Icon in Applications to try to start the application and received a pop-up window saying “Authentication is needed to run the ‘/etc/vnc/vncservice’ as the super user’. But no GUI appeared.
I ran the following to check if the service was running:
$ sudo systemctl status vncserver-x11-serviced.service

Oct 29 13:36:13 user vncserver-x11[9403]: ConsoleDisplay: Cannot find a running X server on vt2
So I have a few questions:
- Is the lack of VNCServer GUI related to the ConsoleDisplay Error? I think I’ve read that Wayland needs to be disabled in order for this to work, but when I disable Wayland, the display becomes completely unreadable when because I use this desktop outside of VNC.
- Any suggestions on how to get this to work?
Thanks!
