Mac OS Installation Errors with Multiple macOS Versions

Hello.

I have a 2018 Mac Mini with an Intel Processor. It originally came with Catalina and was eventually upgraded to Ventura. Towards the end of Ventura, macOS updates would not install, nor could were upgrades to a new operating system. There were error messages about problems preparing the update.

After various attempted fixes not working, I moved all the files to a different computer and tried to reinstall Ventura through Recovery Mode and a USB. Both failed (with an error message that a software update was needed to proceed--which failed.) I did an erase of the disk and in Internet Recovery Mode I was able to successfully reinstall Catalina and then do successfully do a Catalina update.

However, I have tried to install Sequoia, Ventura and Monterey and they all fail. Every time it fails showing 8 minutes left with the error message, "An error occurred installing macOS. You can try again to complete the installation." The Mac Mini is connected to the Internet with an Ethernet connection, so I don't think the connection is the problem. I have run the Disk Utility first aid tool numerous times and not come across any problems. I have also tried the install in Safe Mode.

Any ideas????
