Getting error on installing bootstrap subtheme? Why i am getting this error "Unable to install bootstrap_subtheme, THEMENAME.settings has unmet dependencies". ?

Also my themename.theme file showing error on renaming "The item could not be renamed." for removing this error i created a clone blank file with name bootstrap_subtheme.theme and copy content of original themename.theme file ,paste it into the bootstrap_subtheme.theme file and finally deleted the original themename.theme file.

Still i am getting the following error Unable to install bootstrap_subtheme, THEMENAME.settings has unmet dependencies.
I was getting the same error message and here's how I fixed it.  In your subtheme folder (docroot/themes/bootstrap_subtheme) there's a config folder with two subfolders: install and schema.  Each of these subfolders has a YML file with THEMENAME in the file name, I just changed THEMENAME to my subtheme name and then I was able to install my subtheme.
