cannot update from monterey to ventura

I use a Macbook Air 2020, 13", Retina, 8G, Monterey 12.6.6. I have been unsuccessful in all attempts to upgrade to Ventura. The download can take days to complete, and then when it finally starts to install, it fails. Advice appreciated!

MacBook Air 13″, macOS 12.6

How is the computer connected to the Internet ?


For better and more reliable results, connection via an Ethernet Cable to Router


Switch to a different Wifi Network either at home or Office, Friend, Associate, School, University, Coffee Shop etc


Software on the computer interfering with the download process including AntiVirus Software


Notation: Disabling the AV Software may or may not solve the issue. Removal of the AV Software may increase the chances of the download to perform as expected.


5 - Running behind a VPN which may increase Packet losses or corruption of the download

It's connected via wifi. I know that there are some dead spots, so connecting directly to the router makes good sense. I had disabled the AV software previously but had not considered removing it, so that gives me something else to try. I hadn't thought about VPN but that is definitely something to look into further. Thanks for some great suggestions!
