CentOS 9 Stream - 执行 yum 更新时出错

Question

我刚刚使用 Ubuntu。

刚刚在我的 DEV 服务器上安装了 CentOS，并且在进行更新或安装新软件包时立即遇到问题。

这是错误：

sudo yum update

Error:

 Problem 1: problem with installed package libidn2-2.3.0-7.el9.x86_64
  - cannot install the best update candidate for package libidn2-2.3.0-7.el9.x86_64
  - nothing provides libunistring.so.0()(64bit) needed by libidn2-2.3.2-1.el7.x86_64

 Problem 2: cannot install the best update candidate for package python3-tracer-0.7.5-4.el9.noarch
  - problem with installed package python3-tracer-0.7.5-4.el9.noarch
  - package python3-tracer-0.7.5-4.el9.noarch requires tracer-common = 0.7.5-4.el9, but none of the providers can be installed
  - cannot install the best update candidate for package tracer-common-0.7.5-4.el9.noarch
  - cannot install both tracer-common-0.7.8-1.el7.noarch and tracer-common-0.7.5-4.el9.noarch

以下是已启用的存储库：

yum repolist enabled
repo id       repo name
appstream     CentOS Stream 9 - AppStream
baseos        CentOS Stream 9 - BaseOS
epel          Extra Packages for Enterprise Linux 7 - x86_64
extras-common CentOS Stream 9 - Extras packages
remi-safe     Safe Remi's RPM repository for Enterprise Linux 7 - x86_6

我尝试过：

sudo yum update --best --allowerasing

但它仍然抱怨：

Problem 1: problem with installed package libidn2-2.3.0-7.el9.x86_64
  - cannot install the best update candidate for package libidn2-2.3.0-7.el9.x86_64

 Problem 2: cannot install the best update candidate for package python3-tracer-0.7.5-4.el9.noarch

  - cannot install the best update candidate for package tracer-common-0.7.5-4.el9.noarch
  - cannot install both tracer-common-0.7.8-1.el7.noarch and tracer-common-0.7.5-4.el9.noarch
(try to add '--skip-broken' to skip uninstallable packages)

任何想法如何解决这一问题？

更新：

尝试过

yum clean all
yum check
yum check-update
yum update

Answer 1

baseos CentOS Stream 9 - 适用于 Enterprise Linux 7 的 BaseOS epel 额外软件包 - x86_64 extras-common CentOS Stream 9 - 额外软件包

当您运行 EL-9 时，您正在使用旧的 EPEL（和“remi”）作为 EL-7

您需要删除 epel-release 和 remi-release 并安装正确的版本。
