执行 yum update 时出错“best candidate”

Question

执行sudo yum update时如何解决以下错误

#sudo yum update
Error:
 Problem 1: cannot install the best update candidate for package netdata-1.30.1-2.el8.x86_64
  - nothing provides libjson-c.so.4(JSONC_0.14)(64bit) needed by netdata-1.37.1-1.el8.x86_64
 Problem 2: package netdata-1.30.1-2.el8.x86_64 requires netdata-conf = 1.30.1-2.el8, but none of the providers can be installed
  - cannot install both netdata-conf-1.37.1-1.el8.noarch and netdata-conf-1.30.1-2.el8.noarch
  - problem with installed package netdata-1.30.1-2.el8.x86_64
  - cannot install the best update candidate for package netdata-conf-1.30.1-2.el8.noarch
  - nothing provides libjson-c.so.4(JSONC_0.14)(64bit) needed by netdata-1.36.1-1.el8.x86_64
  - nothing provides libjson-c.so.4(JSONC_0.14)(64bit) needed by netdata-1.37.1-1.el8.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)

Answer 1

尝试清理缓存，然后更新。

# sudo yum clean all
# sudo yum check
# sudo yum check-update
# sudo yum update

如果仍然存在问题，请尝试使用 sudo yum update --nobest 命令。
