could not create a reboot volume for apfs install
iMac, intel, catalina, I'm trying to erase the hard drive to trade in, and after erasing the disk it stalls on re-installing the OS and gives me the error: "could not create a reboot volume for apfs install"
If I restart I get the question mark screen
How do I fix this?
iMac 21.5″, macOS 10.15
