report error
reason
According to the error message, it was shown that msql-clinet was deprecated. After Baidu found that many "is needed" lacked related dependency packages and needed security packages, but mine was deprecated, and then continued Baidu's accidental discovery, only need to add after the command --force --nodeps will do. (The specific reasons are still being explored)
