When updating the code, I suspected that there was a problem with the download speed, so I restarted the computer, and when I came to update again, the following error occurred within a few seconds
Then I clean up and update again, but it still happened again after a while
Solution: Try a few more times and it's ok. I'm like this. Anyway, I didn't find a solution on the Internet, so I was tossing about it. After a few more attempts, you can continue to download the code.
