在经过相当标准的安装过程之后，我无法让 Jenkins 在 Fedora 27 上运行。
dnf install jenkins
systemctl start jenkins

我在 2 个 Fedora 安装中都遇到了这个问题。我更新了所有软件包。我不知道如何修复这个问题。消息日志中没有提示。有人能帮忙吗？
答案1
看起来这是一个Fedora 27 版 Jenkins 软件包依赖项存在错误。
错误报告中建议的一个解决方法是使用 RHEL 的一个 rpm 包pkg.jenkins.io而不是官方的 Fedora 软件包。
答案2
尽管正如评论中指出的那样，我找到了一种可行的解决方法，但我不确定这是否是一种安全的解决方法。
这是dnf upgrade --best --allowerasing jenkins
jenkins-webtool 软件包的依赖关系已损坏，无法正常升级到 2.x 版本。这个问题确实应该在 fedora 软件包中修复。
