Hello,
I migrated from guacamole-1.0.0 to guacamole-1.2.0 on Ubuntu 18.04. But my remoteapp on Windows server 2019, is getting disconnected as soon as I click/move the mouse over the remote app. I did the following steps 1. Ensure all required dependencies are in place for 1.2.0 sudo apt install -y libcairo2-dev libjpeg-turbo8-dev libpng-dev libtool-bin libossp-uuid-dev Note: It did not accept libpng12-dev as per guacamole manual sudo apt install -y libavcodec-dev libavformat-dev libavutil-dev libswscale-dev freerdp2-dev libpango1.0-dev libssh2-1-dev libtelnet-dev libvncserver-dev libpulse-dev libssl-dev libvorbis-dev libwebp-dev 2. stop tomcat and guacd 3. remove existing guacamole-server directory sudo rm -r /etc/guacamole-server-1.0.0 4. Install guacamole server 1.2.0 in /etc/ sudo tar -xzf guacamole-server-1.2.0.tar.gz cd guacamole-server-1.2.0/ sudo./configure --with-init-dir=/etc/init.d sudo make sudo make install sudo ldconfig sudo update-rc.d guacd defaults 5. Remove guacamole.war and guacamole/ from /var/lib/tomcat8/webapps 6. Copy guacamole.war to tomcat8 cp guacamole-1.2.0.war /var/lib/tomcat8/webapps/guacamole.war 7. Restart tomcat8 and guacd Tomcat8 logs: Sun Jul 05 18:19:25 IST 2020 WARN: Establishing SSL connection without server's identity verification is not recommended.
