Installing VNC on Raspberry Pi 3B+ with Ubuntu 20.10 32bit

This was done so that the enablement of RealVNC on Raspberry PI 3 B+ running Ubuntu Groovy Gorilla (20.10) 32bit could work

Found this on: https://www.raspberrypi.org/forums/viewtopic.php?t=288769[](https://www.raspberrypi.org/forums/viewtopic.php?t=288769)

The folks that inspired me to write this bash script to help others are soma72 for the original instructions, pucasso, kazin08 and Ghost_Rider51 for cracking the code With their instructions below

The steps documented to work

# Download package required
# source: http://archive.raspberrypi.org/debian/pool/main/r/realvnc-vnc/
wget https://archive.raspberrypi.org/debian/pool/main/r/realvnc-vnc/realvnc-vnc-server_6.7.2.42622_armhf.deb

# Install package
sudo dpkg -i realvnc-vnc-server_6.7.2.42622_armhf.deb

# Change over to the arm-linux-gnueabihf folder under /usr/lib
cd /usr/lib/arm-linux-gnueabihf

# As sudo create symlinks to the following files
sudo ln libvcos.so /usr/lib/libvcos.so.0
sudo ln libvchiq_arm.so /usr/lib/libvchiq_arm.so.0
sudo ln libbcm_host.so /usr/lib/libbcm_host.so.0
#libbcm_host.so
# libvcos.so
sudo ln libmmal.so
sudo ln libmmal_core.so
sudo ln libmmal_components.so
sudo ln libmmal_util.so
sudo ln libmmal_vc_client.so
sudo ln libvcsm.so
sudo ln libcontainers.so

sudo systemctl enable vncserver-virtuald.service
sudo systemctl enable vncserver-x11-serviced.service
sudo systemctl start vncserver-virtuald.service
sudo systemctl start vncserver-x11-serviced.service
# sudo reboot

Script to autoinstall

This will be helpful when having to do this across several RPis. BASH Script based on those documented steps.

install-real-vnc-server-rpi3-ubuntu20.10.sh

To run it you must run as sudo

# chmod the script first
chmod +x install-real-vnc-server-rpi3-ubuntu20.10.sh

sudo ./install-real-vnc-server-rpi3-ubuntu20.10.sh

E.g.

You are about to install RealVNC Server for Raspberry Pi 3
realvnc-vnc-server_6.7.2.42622_armhf.deb
Running OS Ubuntu 20.10 32bit


Would you like to continue?
Enter 'y' for yes or 'n' for No :

System needs to be rebooted.
Would you like to reboot it now?
Enter 'y' for yes or 'n' for No :
n
# No was selected
No worries you can always reboot when you are ready.
You can reboot with the command
'sudo shutdown -r now'

That is pretty much it. Please feel free to modify the logic in script to make it better.
