Install RealVNC server on arm64 linux (Ubuntu on RasPi)

install-realvnc-server-linux-arm64.sh

mkdir realvncserversetup && cd realvncserversetup
echo Add armhf arch
sudo dpkg --add-architecture armhf && sudo apt update

echo Download and install RealVNC server
wget -nv https://www.realvnc.com/download/file/vnc.files/VNC-Server-6.7.4-Linux-ARM.deb && sudo apt install ./VNC-Server-6.7.4-Linux-ARM.deb

echo Download and install dependencies
files=( libbcm_host.so libvcos.so libmmal.so libmmal_core.so libmmal_components.so \
	libmmal_util.so libmmal_vc_client.so libvchiq_arm.so libvcsm.so libcontainers.so )
for i in "${files[@]}"
do
	wget -nv https://github.com/raspberrypi/firmware/raw/master/opt/vc/lib/$i
done
sudo mv *.so /usr/lib/
cd ..

echo Enable VNC service on boot
sudo systemctl enable vncserver-x11-serviced.service
echo Start VNC service
sudo systemctl start vncserver-x11-serviced.service

on jetson nano arm64 it does not work :

/usr/bin/vncserver-x11-core: error while loading shared libraries: libbcm_host.so: wrong ELF class: ELFCLASS64

I'm getting an error message on line 9, it fails to download and install dependecies. At first it complained about an unexpected "(", I've removed both parenthesis and put all filenames in one line, but now it fails to find "libvcos.so".
I'm running Ubuntu 21.04 64bit on a Raspberry Pi 4. Updating from 20.10 broke my RealVNC server installation, as well as uninstalled any python modules I had installed via pip...But that's just a side note :P

I didn't understand if at the end,you have been able to make it work or not. If yes,please write here the commands that you have issued. thanks.

unfortunately, I have not been able to get RealVNC to work. I'm currently using x11vnc, which needed me to disable the "wayland" windowmanager, as well as needed a manual entry as service to enable starting the VNC server on startup. I've not yet been able to make it use encrypted connections, so I do get warnings from my VNC client software (on windows and android).

what do u think about using remmina as client and xrdp as server ? it supports the audio,VNC doesn't. I'm trying to accomplish this task.

I don't have any experience with both remmina as well as xrdp. I've always used RealVNC as a VNC provider for my raspberry pi systems ( two Pi 3B+, one Pi 4, two RPi Zero W) or, where graphical interface was not needed, SSH.
For windows systems, I'm using Teamviewer.
As far as I understand it, you're trying to connect from a Unix / Ubuntu PC to a raspberry? If so, my guess is that using your described software should work.

I've installed remmina --version 1.4.17 (git n/a) on FreeBSD 13 and xfreerdp = 2.3.0 server on Ubuntu 21.04 emulated with bhyve on FreeBSD 13. I've chosen remmina + xrdp because it supports the audio. VNC doesn't. If u use VNC and VNC does not support audio,how can you hear the music coming from the youtube videos,for example ?

I'm sorry, but I don't use the remote connection for such things, I'm using the remote connection for programming and working on the remote system. I don't need sound, as I only do programming in Python, as well as maintaining installed software.
