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.
