I have been wanting to install a new update macOs 11.2.1 for a few days, but despite trying with several different internet, I still can't and it gives this message :

I am going to suggest that you are using Wi-Fi to do the download and it is not working. This is because most Wi-Fi is too slow for these very large files and corruption often occurs. Try using a wired Ethernet connection instead. Stay off of the internet during the download. It can take up to an hour, more or less to download. If it is not possible to use a direct wired connection, you may have to do a number of lengthy downloads until you get a clean one that works.
