Cannot install Big Sur updates

Since upgrading to Big Sur I have been having problems installing OS updates. It started with 11.1. After seemingly downloading the update, the update would fail to install and a notification would appear saying to try again later. Eventually, I got tired of this and I reinstalled Big Sur from scratch. The OS installed with the latest update when a fresh install was performed.


I am now trying to install 11.2 (and today 11.2.1) and after about 20 minutes downloading the update, I get an error saying the download has failed because an error occured while downloading the selected updates.


Honestly, this is getting annoying, and I cannot reinstall the OS every time there is an update. I am seriously considering downgrading to Catalina instead, which was a much better OS anyway.


Any help which can be provided would be much appreciated.

Updating Big Sur is one of the biggest issues with this 11.0 OS. The only way that I could update Big Sur was to backup my computer, and then format the hard drive. Nothing else worked, not even recovery. Then install Big Sur on the empty hard drive, and then copy over all of my data. Using CCC to backup the data was quick and easy.


Trying to update 11.0.1 was a pain.

Trying to update 11.1 was a pain.

Trying to update 11.2 was a pain.

Trying to update 11.2.1 was quick and easy.


Hopefully whatever the issue was is now fixed, but you'll need to get 11.2 installed first. then install 11.2.1.
