Java Apache Karaf（4.2.6）shell:无法安装webconsole

我正在尝试一个功能：在Karaf 4.2.6版中安装webconsole，但在我尝试设置Karaf的每台机器上，我都会收到以下错误消息：

Error executing command: Error:
        Error downloading mvn:org.apache.karaf.webconsole/org.apache.karaf.webconsole.instance/4.2.6

不管是Windows还是LinuxMint，我都无法安装webconsole。我已经卸载并重新安装了Java 1.8.0_241和Maven 3.6.3，并在这两个操作系统上设置了各自的环境变量

我错过什么了吗

以下是完整的控制台日志：
