Thanks for your interest on using Bitnami. Can you please give us more information about your system? Which Linux distro and version are you using? Can you share with us the link to your Intel NUC specifications? Can you also please run the commands below and paste here the output?
sudo cat /etc/*release
sudo uname -a
Also, can you let us know which command were you using to run the Bitnami Jenkins stack installer? Can you try to run the commands below to start it in text mode?
sudo chmod +x bitnami-jenkins-2.176.1-0-linux-x64-installer.run
sudo ./bitnami-jenkins-2.176.1-0-linux-x64-installer.run --mode text
If it doesn't work, can you please run it in debug mode and send us the `trace.txt` file? You can upload that file a DropBox or Google Drive account and share with me the download link using the direct message I have already sent to you.
sudo ./bitnami-jenkins-2.176.1-0-linux-x64-installer.run --mode text --debugtrace "trace.txt"
