I am currently getting this error when installing a new app on the new snapshot. I thought I had used luci-compat in the past to fix similar error, but that is not working. Is there something else that can be used?
Does anyone know what can be done to fix the Insufficient permissions to read UCI configuration error?
It should work by default, otherwise you likely have something configured incorrectly.
chmod -R go+rX /etc/config
ACL rules restrict that in master. It is not only about file permissions, but LuCI modules have restrictions for their permitted actions.
