Ubuntu 16,預設有安裝modem manager, 但是未啟動

指令mmcli會得到如下錯誤

gcat@ubuntu:~$ mmcli -L

error: couldnt find the ModemManager process in the bus

gcat@ubuntu:~$ mmcli -L

error: couldnt find the ModemManager process in the bus

查詢

systemctl status ModemManager

● ModemManager.service - Modem Manager

   Loaded: loaded (/lib/systemd/system/ModemManager.service; disabled; vendor pr

   Active: inactive (dead)

修正

sudo systemctl enable ModemManager

sudo systemctl start ModemManager

測試

#scan modem

mmcli -S

#list modem

mmcli -L

若有插入EC20, 

右上角的Network manage內, 會出現Enable Mobile Broadban

===========

建議使用

sudo snap install modem-manager

以免有其它奇怪的問題
