After adding Tsinghua’s mirror website here, updating Anaconda may still cause the following problem: condaHTTPError

• Enter the modification settings on the command line conda config --set ssl_verify false, or /.condarcadd a line at the end of the file ssl_verify: false(you can modify it if there is one)
• Change https to http

Cause Analysis

The https protocol has more authentication and encryption stages such as SSL and TLS than the http protocol. There may be problems in the process of SSL authentication with Tsinghuayuan, so it is necessary to turn off SSL authentication or use the http protocol instead. But the use of SSL verification is helpful to ensure the reliability of the transmission process.
