Can't unlock UMTS modem with PIN

[Andreas Weller]

I can't unlock my UMTS USB modem with Lubuntu 15.04 (It works on xubuntu 14.10)

(nm-applet:3280): nm-applet-WARNING **: Failed to send PIN to devid: 'c8efb515c36471e33a1e711a672ed5cb45b5c5a2' simid: '(null)' : PolicyKit authorization failed: challenge needed for 'org.freedesktop.ModemManager1.Device.Control'

lsusb output:
Bus 003 Device 005: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E230/E270/E870 HSDPA/HSUPA Modem

usb-modeswitch usb-modeswitch-data is installed.

Any idea?

Thank you!

Status changed to 'Confirmed' because the bug affects multiple users.

[Hugo Otto (hugootto)]

Exactly the same with me. Works with Ubuntu 15.04.

If you use the workaround at #1424362:

WORKAROUND
 1. open Default Apps for LXSession
 2. click on "autostart tab"
 3. make sure "PolicyKit Authentication Agent" is checked
 * NOTE: works on a per user basis

…is this fixed?

If so, please mark it as a dupe.

If it is not, then we need some more information. Specifically, I would like to know if this affects any other network manager tasks and if so, which. I'd start with Ethernet since everyone has that and it's easy to test. Also, having very clear steps to reproduce would be great.

Thus, I'm going to call it incomplete.

The workaround at #1424362 works.
Finally I can unlock 3G modem's SIM.

So I'll mark this bug as duplicate.

But now it asks once for the PIN and then for the current user's password. Is this really necessary?
