I searched for this problem but couldn't find any information on it. I am a new Linux user so I am not aware with the strong codes used. Kindly provide every detail if you have done it. Find the Android cm os here: https://osdn.net/projects/android-x86/downloads/68670/cm-x86-14.1-r4.i686.rpm/
I have converted the .rpm file to .deb file but can't figure out what do do next, please help me and don't delete my question.
To install a .deb file, run
sudo dpkg -i file.deb.
You should probably also read the description on the homepage, and the referred How to Install: https://www.android-x86.org/installhowto.html
On that page I don't see any description on how to install the .rpm file or what it contains. But there are a fine description on downloading and installing from a .iso image.
