macOS could not be installed on your computer

I recently ran into the error "macOS could not be installed on your computer. The path /System/Installation/Packages/OSInstall.mpkg appears to be missing or damaged." message while trying to upgrade my current macOS. I followed the below steps, restored my Time Machine backup, and check for free space, and did the update again and it worked.

Some Solutions:
  • Restart your macOS system by pressing the power button.
  • Check that you have enough storage available for the installation. Free up space if required. I have a 256 GB SSD store and it was almost full.
  • If it does not work, restart your Mac by pressing the power button and reinitiate the installation. Press Command (⌘) + R button to get into the recovery mode. You can either "Recover from Time Machine backup" or try installing macOS again.

✏️ Also make sure that the date and time is set correctly
