startosinstall failed with return code 15. Please verify that the recovery partition is not older than the macOS you are trying to install, and verify that the certificate used to sign the install package is not expired.
I just updated the installer to 10.15.3 and now getting this error. Any fix?
Look in /var/log/install.log to see the specific error message. Run:
cat /var/log/install.log
