RealVNC Server on UBUNTU 20.10 (ARM64) on Raspberry Pi 4 (8GB) by jorgemtds

출처:RealVNC Server on UBUNTU 20.10 (ARM64) on Raspberry Pi 4 (8GB) by jorgemtds - Raspberry Pi Forums

the way i solve this, is to download the the REALVNC debs from the raspberry Debian pool
check the apt source files
make sure you download the arm64 debs
then install via dpkg -i,
do NOT do the systemctl enable and start vnc server bit yet

because - you are going to get 3 errors regarding

libvcos.so
libvchiq_arm.so and
libbcm_host.so

just create links for the files it needs using the ones that were installed via the debs

then open a new terminal, and run the systemctl enable and start then you should see the vnc logo pop up in the top right

Just for clarify this.

Download REALVNC server 64bit deb from here https://archive.raspberrypi.org/debian/ ... _arm64.deb and install it using dpkg or using SSH:

wget https://archive.raspberrypi.org/debian/pool/main/r/realvnc-vnc/realvnc-vnc-server_6.7.2.43081_arm64.deb
sudo dpkg -i realvnc-vnc-server_6.7.2.43081_arm64.deb

wget https://archive.raspberrypi.org/debian/pool/main/r/realvnc-vnc/realvnc-vnc-server_6.7.2.43081_arm64.deb sudo dpkg -i realvnc-vnc-server_6.7.2.43081_arm64.deb

Then you have to create a link for the 3 files that are in the folder /usr/lib/aarch64-linux-gnu to the folder /usr/lib and the link has to end with .0:

cd /usr/lib/aarch64-linux-gnu
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

 

cd /usr/lib/aarch64-linux-gnu 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

After that, you have to enable the 2 services and start it and reboot the pi:

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

 

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
