由于政策包无法启用sierra

Question

我有一台运行ubuntu16.04和mmcli1.6.4的机器，安装了一个Sierra MC7710调制解调器。目前正在显示

mmcli -m 0 -w
/org/freedesktop/ModemManager1/Modem/0: Initial state, 'disabled'

当我试着启用它时

mmcli -m 0 -e

我得到以下错误

error: couldn't enable the modem: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Failed: PolicyKit authorization failed: 'GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.PolicyKit1 was not provided by any .service files''

Answer 1

卸载策略包并重新安装

sudo apt-get install policykit-1

然后命令就起作用了。
