Excuse for delaying me so much but it I found the solution and I forgot to post here, thanks for trying to help me.
This is the link of the solution that I found:
When Cnchi comes to “Checking integrity” appears “Can’t install necessary packages. Cnchi can’t continue”.
I have the latest stable version of the ISO
Already I’ve been trying to install it for some time but each time gives me a different error or bug and now is this becoming something annoying, I will continue trying to install it but this could cause others to stop it trying to install
Sorry if there are errors but I do not speak well in English.
