Once you see this error, you will only have the option to restart the system and try again. If you are seeing this error then it, most probably, will not be solved after a reboot. This means that this error message will prevent you from updating to a newer version. We aren’t sure of the exact error that causes this but it most likely is an issue with the update via the App Store. That is why the most common solution for this is to use a Bootable USB to install the new update. One thing that can cause this issue is what the error message is saying i.e. the path might be missing or damaged. So, fixing or creating the path resolves the issue. Another thing that might cause this is the low disk space. Although it’s not common but a lot of users experienced the issue because of this problem. The thing is, this new update is bigger than usual updates. So, a lot of users miscalculated the space actually needed for this update and got this error.
