I just successfully installed 2.9.5 Ubuntu x64 today on ubuntu VM with steps below:
## Install GPU driver, toolkit, .net SDK... first before execute commands below.
wget
https://codeproject-ai-bunny.b-cdn.net/server/installers/linux/codeproject.ai-server_2.9.5_Ubuntu_x64.zip
unzip codeproject.ai-server_2.9.5_Ubuntu_x64.deb
sudo dpkg -i codeproject.ai-server_2.9.5_Ubuntu_x64.deb
bash /usr/bin/codeproject.ai-server-2.9.5/start.sh
#Wait for Face, YOLOs (by default) installations to finish.
#Check with IP:32168 to make sure CPA server is up
pushd "/usr/bin/codeproject.ai-server-2.9.5/server" && bash ../setup.sh && popd
cd /etc/systemd/system/
#Check for file name codeproject.ai-server.service
sudo systemctl daemon-reload
sudo systemctl enable codeproject.ai-server.service
sudo systemctl start codeproject.ai-server.service
# to auto start codeproject server after reboot
# you might have to execute sudo dpkg -r codeproject.ai-server to remove previous install.
Hope this helps.
