Error:
Problem: cannot install both mysql-common-8.0.30-1.module el8.6.0 352 98f9a3f3.x86_64 and mysql-common-8.0.26-1.module el8.6.0 142 9a84cdf3.x86_64
- package mysql-8.0.26-1.module el8.6.0 142 9a84cdf3.x86_64 requires mysql-common(x86-64) = 8.0.26-1.module el8.6.0 142 9a84cdf3, but none of the providers can be installed
- cannot install the best update candidate for package mysql-common-8.0.26-1.module el8.6.0 142 9a84cdf3.x86_64
- problem with installed package mysql-8.0.26-1.module el8.6.0 142 9a84cdf3.x86_64
(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)看着提示是有包冲突，然后又跳过这个包执行了
代码语言：javascript复制yum update --allowerasin -y结果跑了大概不到1分钟吧，跳出来新的错误
