Ubus hostapd missing

Hi everyone,

I have a device with:

DISTRIB_ID='OpenWrt'
DISTRIB_RELEASE='19.07-SNAPSHOT'
DISTRIB_REVISION='r0-7e0a8ca'
DISTRIB_TARGET='ar71xx/generic'
DISTRIB_ARCH='mips_24kc'
DISTRIB_DESCRIPTION='OpenWrt 19.07-SNAPSHOT r0-7e0a8ca'
DISTRIB_TAINTS='no-all busybox'

The following packages are installed:

hostapd-common - 2019-08-08-ca8c2bd2-4
hostapd-utils - 2019-08-08-ca8c2bd2-4
wpad - 2019-08-08-ca8c2bd2-4
rpcd-mod-iwinfo - 2020-05-26-67c8a3fd-1

Yet there's no hostapd ubus interface:

# ubus list
dhcp
dnsmasq
iwinfo
log
network
network.device
network.interface
[...]
network.wireless
service
session
system
uci

I'm wondering, is there any dependency missing? What's wrong with this device?

I'm not sure how I fixed it, after a few reboots and configuration changes the problem disappeared.

(hostapd registers on ubus only if it does correctly load and run so probably it was just a configuration problem that crash the hostapd process)

I think you are right. Thanks for clarifying.
