Mock DNF transaction conflict "X conflicts with file from package Y"

In mock i am getting a DNF transaction error conflict. I am new to mock, i assume this is a upstream conflict?

Error: Transaction test error:
file /usr/lib64/ from install of ncurses-lib-6.4.20230708-79.x86_64 conflicts with file from package ncurses-lib-narrow-6.3-65.x86_64

It is from a ClearLinux Autospec enviroment, I also posted this question on ClearLinux github here

make mockclean fixed it
