Internal server error (unable to find section 'main')

Hi Guys,

I think I have the same situation as in issue #1803 . D-Link DWR-118 A2 fresh snapshot install tried hard reset etc etc.

/usr/lib/lua/luci/dispatcher.lua:247: /etc/config/luci seems to be corrupt, unable to find section ‘main’ stack traceback: [C]: in function ‘assert’ /usr/lib/lua/luci/dispatcher.lua:247: in function ‘dispatch’ /usr/lib/lua/luci/dispatcher.lua:144: in function </usr/lib/lua/luci/dispatcher.lua:143>

ls -la /etc/config/luci

-rw-------    1 root     root           793 Jun 21 14:38 /etc/config/luci

grep “main” /etc/config/luci

Anybody who reads this, the solution is the following: Link the new library file to the old name in /usr/lib:

root@OpenWrt:~# cd /usr/lib
root@OpenWrt:/usr/lib# ln -s libjson-c.so.4.0.0 libjson-c.so.2

Then it works as it should, and LuCi works too! 😃

root@OpenWrt:~# service rpcd start
root@OpenWrt:~# ps | grep rpcd
 5045 root      1548 S    /sbin/rpcd -s /var/run/ubus.sock -t 30

@odon-noda confirmed. it is rpcd problem. cd /tmp wget http://downloads.openwrt.org/snapshots/packages/mips_24kc/base/rpcd_2019-09-01-821045f6-3_mips_24kc.ipk opkg install rpcd_2019-09-01-821045f6-3_mips_24kc.ipk --force-downgrade worked.
