Each tine i've tried to download Monterey, I get an error message. I have enough space for the upgrade, so what is the problem?

My System Preferences shows that I can upgrade to Monterey. (I have Big Sur) but each time I try to download it, I get an error message. One error said the internet connection was not good. But when I tried again, several times, and mostly late evening, it still showed an error, but then didn't say what the error was. What am I doing wrong? (And besides, it's supposed to update automatically)

I suggest trying one or both of the following:

Boot up your Mac in Safe Mode. Then try upgrading again.
If not already, connect your Mac by Ethernet. Then try upgrading again.

Do you have enough free disk space?

If upgrading from macOS Sierra or later, your Mac needs 26GB of available storage to upgrade. If upgrading from an earlier release, your Mac needs up to 44GB of available storage.

Also uninstall any antivirus and "cleaning" apps before trying installing again.

Further, you need an Apple disk installed to upgrade to Monterey since the upgrade includes an update to the Mac's firmware. That update looks for an Apple disk and write to the dick to do the firmware update. The install will terminate or freeze if no Apple disk.

Some users have problem with skipping upgrade versions and even not updating to the latest version of Big Sur.

Is Big Sur running the Most up to dated version 11.6.2 ?

Have seen numerous persons attempting to jump from Big Sur 11.3.1 or 11.4 and even 11.5. directly to Monterey and it will balk at installing Monterey.

There are factors:

1 - Like poor Wifi connection

2 - Slow wifi connection

3 - Too many other people downloading at the same time and Apple Severs are overloaded

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

5 - Running behind a VPN which may increase Packet losses and may corrupt the download

6 - If via wifi too many Other devices using the wifi at the same time reducing the Bandwidth to your computer.

7 - Best Results are via Ethernet Cable to Router

Hello and thank you for the suggestion. I needed to look up Safe Mode, in order to proceed. Safe Mode kick in only after I shut my system down completely and restarted the next morning. My problem may be in the ethernet you mentioned. And I will have to look for an old cable and try again later. Thank you again for your input.

Internet connection was mentioned in my first try to download Monterey, but not in later tries. Tesserax suggested an ethernet connection, also, and I'm going to try that, as soon as I can find my old Tiger cable, if I still have it. I'm not sure about AntiVirus Software, or any other software interfering.

Two of my memory slots are still available, if that means anything about space to do an upgrade.

Hello. I'm sorry to bother you again. I purchased an ethernet cable and connected it to the router and tried the Monterey upgrade again. This time, I got a message: "The package #%@ is missing or invalid. An error occurred while installing the selected updates." I have no idea what that means. Please advise. Thank you.

How to Fix "The package '%@' is missing or invalid" macOS Monterey Upgrade Error

Edited

This maybe because there are existing update to existing version of macOS pending installation. That being sunning Big Sur ( example only ) version 11.6.0 and there is a Big Sur 11.6.2 pending installation.
