Works for me with Reboot (SNAPSHOT, r4960-1114f5d). r4235-61eb18d is from May 2017. You should really update to a recent version before reporting any bugs.

If the issue persist after installing a recent snapshot, please reopen the ticket and provide the following informations:

• on which device does the problem occur?
• does it happened as well if you reset your config to factory defaults?
• please attach your /etc/config/network

The same issue was also observed on the development shapshot build for the bcm53xx target. Sorry, I should have mentioned it in my original bug submission earlier today. The image I used for testing was downloaded on 2017-10-01 from:

http://downloads.lede-project.org/snapshots/targets/bcm53xx/generic/lede-bcm53xx-buffalo-wxr-1900dhp-squashfs.trx

The downloaded image was installed with "sysupgrade -v -n ./lede-bcm53xx-buffalo-wxr-1900dhp-squashfs.trx". I made no configuration changes in any of the files in /etc/config/ after installing the downloaded image.

I also tested this issue on my own LEDE build, LEDE Reboot SNAPSHOT r4967-5508510. The result was the same: "“Command failed: Unknown error".

I can confirm the issue on the current x86_64 snapshot image.

If a device has no wireless interfaces, the uci config for the wireless will fail and netifd's config_init_all() function will return -1: https://git.lede-project.org/?p=project/netifd.git;a=blob;f=config.c;h=a7112f042a677426ab27baff8b8131e0bb4e3d40;hb=HEAD#l424

The return value of -1 then propagates to netifd_reload():
https://git.lede-project.org/?p=project/netifd.git;a=blob;f=main.c;h=c173cef35be5a840d1d9d5d3b67c3eeab3f0c3b0;hb=HEAD#l213

and then to netifd_handle_reload()
https://git.lede-project.org/?p=project/netifd.git;a=blob;f=ubus.c;h=bf7267239ccc7ab16625fc658f1a04cfcc015db7;hb=HEAD#l48

The suggested fix is to check for presence of /etc/config/wireless and return -1 only if the file is present.

Hi,

I am also facing the same issue with ubus.
For me also "/etc/init.d/network reload" not working.
Further nail-down the issue and found "ubus call network reload" not working.

###iotGateway### ubus call network reload
Command failed: Unknown error

The below are my LEDE info:
VERSION="SNAPSHOT, Reboot"
VERSION_ID="snapshot"
HOME_URL="http://lede-project.org/"
BUG_URL="http://bugs.lede-project.org/"
SUPPORT_URL="http://forum.lede-project.org/"
BUILD_ID="r4795-c1563d7"
LEDE_BOARD="mediatek/32"
LEDE_ARCH="arm_cortex-a7_neon-vfpv4"
LEDE_TAINTS="no-all busybox"
LEDE_DEVICE_MANUFACTURER_URL="http://lede-project.org/"
LEDE_RELEASE="Reboot SNAPSHOT r4795-c1563d7"

Can anyone put light on this issue?
Can someone guide me which patch/code changes I have to integrate with my Lede code base to fix this issue?
Note: I have downloaded Lede code base from github and compiled for bananapi-r2 device.

Update to the latest source!

You are using r4795, which should be from somewhat around Wed, 6 Sep 2017 14:46:03 +0100. This fix was committed on Fri, 6 Oct 2017 16:31:21 +0100 to netifd and netifd was updated in LEDE on Thu, 27 Oct 2016 11:45:05 +0100.
