LuCI 500 Internal Server Error: unable to find section 'main'

[initramfs]

Upon using and installing the latest version of LuCI the web interface does not load, yielding this error message:

/usr/lib/lua/luci/dispatcher.lua:230: /etc/config/luci seems to be corrupt, unable to find section 'main'
stack traceback:
    [C]: in function 'assert'
    /usr/lib/lua/luci/dispatcher.lua:230: in function 'dispatch'
    /usr/lib/lua/luci/dispatcher.lua:127: in function </usr/lib/lua/luci/dispatcher.lua:126>

This is irrespective of the actual luci configuration file used (/etc/config/luci), including the default auto-generated config.

[dibdot]

Can't reproduce that, please post the output of ...

ls -la /etc/config/luci grep "main" /etc/config/luci opkg list-installed luci*

[jow-]

This can also mean that LuCI is unable to query uci data via ubus. It is likely caused by enabling uci session isolation.

Please provide the output of ls -l /usr/share/rpcd/acl.d/ and ls -l /usr/share/acl.d/

[initramfs]

ls -la /etc/config/luci:

-rw-------    1 root     root          1078 May 18 22:33 /etc/config/luci

The config file itself (autogenerated):

ls -l /usr/share/acl.d/

-rw-r--r--    1 root     root            50 May  5 03:44 dnsmasq_acl.json
-rw-r--r--    1 root     root            91 May  5 03:44 luci-base.json

Note: I forgot to mention but this manifests as a regression for me, downgrading to a previous build with the same config files works just fine.

[initramfs]

Okay I can confirm that 9ed48ef fixed the regression.

I cant confirm
