安装警报，拖曳在许多Akonadi软件包，但未能启动，并说Akonadi是必需的？

Question

新安装的Kubuntu 19.10

我安装了Kalarm，其中拖拽了其他39个软件包，其中大多数都以"akonadi“或"pim”的名字命名。

然后，我试着启动that，并得到一个面板，上面写着“Akonadi个人信息管理服务没有运行，没有它就不能使用这个应用程序。”就在下面是一个大的“开始”按钮，但点击它什么也做不了。

如果我在终端启动kalarm，我会看到：

org.kde.pim.kidentitymanagement: IdentityManager: There was no default identity. Marking first one as default.
org.kde.pim.kalarm: Preferences::setNoAutoStart: Error writing autostart file: "/home/me/.config/autostart/kalarm.autostart.desktop"
org.kde.pim.akonadicore: Unable to execute akonadi_control, falling back to D-Bus auto-launch

单击“开始”按钮会添加另一个：

org.kde.pim.akonadicore: Unable to execute akonadi_control, falling back to D-Bus auto-launch

创建/home/me/.config/autostart/kalarm.autostart.desktop删除了第2行，但没有解决问题。

有什么想法吗？

版本：

plasmashell 5.16.5
Qt: 5.12.4
KDE Frameworks: 5.62.0
kf5-config: 1.0

编辑:因此安装了mariadb和akonadi服务器(5.11.3)。重新启动。现在开始kalarm说：

 org.kde.pim.kidentitymanagement: IdentityManager: There was no default identity. Marking first one as default.
Failed to register /MainApplication on DBus
""

akonadiselftest报告了两个错误：

• 未找到MySQL服务器默认配置
• 没有找到资源代理

Answer 1

除了它在Kubuntu19.10(最小安装选项)安装时引入的依赖项之外，kalarm还需要额外安装akonadi-server和kdepim-runtime。

这个问题将在不久的将来得到解决:参见这里和这里。
