Regarding wpad and hostapd packages, I was also a little suspicious about them at first, but after searching this forum for the same error string I found other people’s log showing the same warning (regardless their complaints being not the same as mine).

Authenticator.
Interestingly it shows that hostapd package is not installed, but when searching for hostapd string in the opkg list-installed output I found that what I have installed instead was hostapd-common package.
Package: hostapd-common

Should I add same hostapd uninstall config and hostapd-common install at sample.lua file at /etc/updater/conf.d/ directory?
