My online application uses Ubuntu. I selected your file as Linux - Debian based (Ubuntu, etc.), downloaded and extracted it, but found that I couldn’t install it. There are only these three folders, and none of them work. What could be the reason?

Hi @chengjianping

Could you try running this command in terminal and see if that works?

sudo dpkg -i local-10.0.0-linux.deb

It says the core file is missing. I reinstalled your stuff and got the same message
