luci: /usr/lib/lua/luci/dispatcher.lua:370: /etc/config/luci seems to be corrupt, unable to find section 'main'

Update to latest master and restore config from backup (~6 month old), got error: /usr/lib/lua/luci/dispatcher.lua:370: /etc/config/luci seems to be corrupt, unable to find section 'main'

#2885, #2799, #2231 - this is not first time.

Workaroud in this message: https://github.com/openwrt/luci/issues/2231#issuecomment-663915276 work for me: if I run rpcd from ssh then error gone.

I dig inside and found that in my backup /etc/config/rpcd

config rpcd
	option socket /var/run/ubus.sock
	option timeout 30

config login
	option username 'root'
	option password '$p$root'
	list read '*'
	list write '*'

This is from default config after reset:

config rpcd
	option socket /var/run/ubus/ubus.sock
	option timeout 30

config login
	option username 'root'
	option password '$p$root'
	list read '*'
	list write '*'

As you can see:

option socket is different.
if rpcd started without options - if uses proper path to socket, at least GUI works.

Why not remove option socket handling from /etc/config/rpcd and /etc/init.d/rpcd ?

I have been watching real time graphs in luci and top over ssh. CPU eating luci subprocess quit and now I have this error. Restarting rpcd helped.

I too got this after using the real time graphs.

/var/run/ubus/ubus.sock

I upgraded to 21.02 and this happened. changing /var/run/ubus.sock to /var/run/ubus/ubus.sock fixed it, but isn’t this a bug? I don’t know who is to blame, but either the OpenWRT or Luci needs to fix this, so that users don’t have to do this manually.

Same issue after upgrade from 19.07 to Powered by LuCI openwrt-21.02 branch (git-21.163.64918-ba57ec5) / OpenWrt 21.02.0-rc3 r16172-2aba3e9784:

# cat /etc/config/rpcd
config rpcd
	option socket /var/run/ubus.sock
	option timeout 30

config login
	option username 'root'
	option password '$p$root'
	list read '*'
	list write '*'

# ls -latr /var/run/ubus.sock
ls: /var/run/ubus.sock: No such file or directory
# ls -latr /var/run/ubus/
srw-rw-rw-    1 root     root             0 Jan  1  1970 ubus.sock

Editiing the config file to match the /var/run/ubus/ubus.sock and service rpcd restart fixed the issue for me.
