Hello Nada,
I strongly recommend to upgrade to Ubuntu 18.04 based OS.
You can try a workaround with docker (the only I have found so far)
# install docker
apt install docker.io
# enable docker to contact your X server
xhost +
# build docker image with minimal dependencies
sudo docker -t provi - <<EOF
FROM ubuntu:latest
RUN apt-get update && apt-get install -y x11-apps libgtk-3-0 openssl && apt-get clean
ENTRYPOINT ["/opt/nxp/MCUX_Provi_v1/bin/securep"]
EOF
# run the secure provisioning tool in the container
sudo docker run --rm -ti -v /tmp/.X11-unix:/tmp/.X11-unix:rw -v /opt:/opt --env DISPLAY provi
You will probably need to map your data folder into the docker container using additional parameter
-v /home/myuser/data:/data
to map your folder "/home/myuser/data" into the container under folder "/data" like the /opt folder is mapped into the container.
There are few drawbacks using this workaround, e.g. all created files are owner by the "root" user.
Regards,
Libor
