Monterey Upgrade won't complete the install

I have an iMAC 21.5" late 2015 running macOS Big Sur version 11.6. The processor is a 2.8 GHz Quad Core Intel Core i5. I have tried to install the Monterey upgrade but it has stalled at 6 minutes to complete twice.

After the first stall I tried again but the result was the same the second time. Is there something that I can do or is this iMAC too old for the latest Monterey upgrade ?

That you for your help in this matter.

Please follow these steps:

Go to Finder > Go > Applications, and look for the "Install macOS Monterey" App.
Drag it to the Trash & Empty the Trash.
Restart your Mac into Safe Mode: How to use safe mode on your Mac - Apple Support.
Restart back into normal mode.
See: Upgrade to macOS Monterey - Official Apple Support and How to upgrade to macOS Monterey - Apple Support.

I’d like to know the same thing! Mine has been working on installing for over 24 hours. It gets down to about 15min left and restarts. Shutting down and restarting doesn’t help, it just picks up where it left off. In a loop….
