Bug description:
When the user tries to connect using a GSM modem that lacks a SIM
card, NM just gives the user a general connection failure message; it
does not give any hint about the missing SIM card. This can fool the
user into thinking something other is wrong than the fact that he
forgot to insert the SIM card, or inserted it improperly.
Latest modemmanager master branch gives in log:
Feb 2 20:21:24 marius-T1005 ModemManager[1105]: <warn> Modem
couldn't be initialized: Couldn't check unlock status: SIM failure
but there is no indication to the user (nm-applet behaves as if mobile
broadband is unavailable).
Seems I get (from "src/mm-error-helpers.c"):
{ MM_MOBILE_EQUIPMENT_ERROR_SIM_FAILURE,
"simfailure", "SIM failure" },
but should have got:
{ MM_MOBILE_EQUIPMENT_ERROR_SIM_NOT_INSERTED,
"simnotinserted", "SIM not inserted" }
Anyway (any of them should be enough hint to the user), it seems like
the error state is not propagated (src/mm-broadband-modem.c):
static void
iface_modem_initialize_ready (MMBroadbandModem *self,
GAsyncResult *result,
InitializeContext *ctx)
{
GError *error = NULL;
/* If the modem interface fails to get initialized, we will move the modem
* to a FAILED state. Note that in this case we still export the
interface. */
if (!mm_iface_modem_initialize_finish (MM_IFACE_MODEM (self), result,
&error)) {
/* Report the new FAILED state */
mm_warn ("Modem couldn't be initialized: %s", error->message);
g_error_free (error);
mm_iface_modem_update_state (MM_IFACE_MODEM (self),
MM_MODEM_STATE_FAILED,
MM_MODEM_STATE_CHANGE_REASON_UNKNOWN);
/* Jump to the firmware step. We allow firmware switching even in
failed
* state */
ctx->step = INITIALIZE_STEP_IFACE_FIRMWARE;
initialize_step (ctx);
return;
}
Network Manager logs:
