You still haven't answered to my question, though.
Have you build your altcoin with Satoshi's block, just to see it working?
Ok, I am right now on your tutorial, this step:
mironkraft@DESKTOP-Q44IAMD:~$ sudo apt install g++-mingw-w64-x86-64
[sudo] password for mironkraft:

mironkraft@DESKTOP-Q44IAMD:~$ PATH=$(echo "$PATH" | sed -e 's/:\/mnt.*//g')
mironkraft@DESKTOP-Q44IAMD:~$ sudo bash -c "echo 0 > /proc/sys/fs/binfmt_misc/status"
mironkraft@DESKTOP-Q44IAMD:~$ cd depends
-bash: cd: depends: No such file or directory
mironkraft@DESKTOP-Q44IAMD:~$
it fails, unless im using the code wrongly
fixed by going first to cd XXXXCoin folder, then again cd depends and keep coding the next lines
