Need help with linux portable appimage?

Question

linux

There are seemingly 2 ready-made instructions https://xakep.ru/2011/04/27/55227/ and https://losst.ru/portativnye-programmy-v-linux.
But here's the problem, it still doesn't work. Installed libraries.
And that's it. The goal is to create a portable miner with a deb package located at https://ru.minergate.com/downloads/gui for ubuntu 14....
Problems from the very beginning at the stage (Let's go directly to creating a portable Linux program, open AppDirAssistant, to do this, in the terminal, go to the folder with the program and execute:
cd /Folder/C/Program/
$ ./AppDirAssistant\ 0.3.1)
Nothing starts ......
According to the instructions from the hacker at the stage (And rename the resulting directory so that its new name ends with .appdir:
$ mv data package.appdir)
The directory is not one, what? as? where do I not understand? Help clarify how to create a portable package from this package. In turn, for the help, I undertake to buy a domain, install hosting and write out detailed instructions for dummies on this issue and help people who are also starting to master linux.
