【解決方案】
Solution Authentication to host 'localhost' for user 'root' using method 'mysql_native_password' failed with message: Reading from the stream has failed. while database update, the following solution for the Problem: 1. Press Win+R to open the "Run" dialog 2. Type "gpedit.msc" (without quotes) and press Enter 3. In the "Local Group Policy Editor", expand "Computer Configuration", expand "Administrative Templates", expand "System", expand "Internet Communication Management", and then click "Internet Communication settings". 4. In the details panel, double-click "Turn off Automatic Root Certificates Update", clickEnabled, then click OK. This change will be effective immediatelly without restart. After that, the repair task for the aborted Update went through.
截圖：cmd 運行 gpedit.msc
找到【管理模板】-【Internet通信設置】，
右鍵【關閉自動根證書更新】-點擊【編輯】-改為【已啟用】
再次運行安裝程序：
server安裝成功！
記得把sampling and examples也reconfigure/安裝下，因為需要輸入root密碼。
------------調試記錄，以下請忽略---------

上面標黃的路徑，找該文件：C:\Users\Administrator\AppData\Local\Temp\77f675c3-f387-4b4a-9c92-354bb12093ae.ini ，發現沒找到。
通過服務找到mysql服務對一個文件“my.ini”
"C:\Program Files\MySQL\MySQL Server 8.0\bin\mysqld.exe" --defaults-file="C:\ProgramData\MySQL\MySQL Server 8.0\my.ini" MySQL80-2
# Path to the database root datadir=C:/ProgramData/MySQL/MySQL Server 8.0/Data # The default character set that will be used when a new schema or table is # created and no character set is defined # character-set-server= # The default authentication plugin to be used when connecting to the server default_authentication_plugin=caching_sha2_password
修改為：mysql_native_password
發現沒有用。。還是報原來的錯誤。
最后只能重新安裝server，然后選擇 legacy模式，不要選擇sha2模式。
也同樣報錯：

MySQL error 0: Authentication to host 'localhost' for user 'root' using method 'mysql_native_password' failed with message: Reading from the stream has failed.
