Description

We on Ubuntu 18.04. We were on 2.0.6293 (2021-09-10) and updated to 2.0.6433 (2021-10-07). Jitsi-videobridge was 2.1-551-g2ad6eb0b-1 and now 2.1-570-gb802be83-1

We have JAVA_SYS_PROPS="-Dconfig.file=/etc/jitsi/videobridge/jvb.conf in our /etc/jitsi/videobridge/config file.

We had JVB_OPTS="--apis=rest," in our /etc/jitsi/videobridge/config file. Also (and most important) we have this in /etc/jitsi/videobridge/jvb.conf file

videobridge {
  apis {
       rest {
      enabled = true
    }
  }
  http-servers {
    public {
      port = 9090
      tls-port = 443
    }
    private {
      host = 127.0.0.1
    }
}

So, according to https://github.com/jitsi/jitsi-videobridge/blob/master/doc/statistics.md and mostly https://github.com/jitsi/jitsi-videobridge/blob/master/doc/rest.md we should be enabled Colibri REST API that way (jvb.conf file)

But after update we get JVB_OPTS="--apis=," in our /etc/jitsi/videobridge/config file! And all conference statistic gone. I mentioned it here https://github.com/jitsi/jitsi-meet/issues/10415

So, now I have 2 questions:

1. Why update postinst script deleted rest in --apis?
2. Why Colibri REST API don’t work despite enabled in jvb.conf file?

Current behavior

Statistics gone during update to recent jitsi-videobridge2 packet.

rest is always enable = true in jvb.conf file but I get this results: with JVB_OPTS="--apis=rest," in our /etc/jitsi/videobridge/config file I get

Here is open ports with both JVB_OPTS="--apis=," and JVB_OPTS="--apis=rest," in our /etc/jitsi/videobridge/config

netstat -tulnp

Active Internet connections (only servers)

I see this https://github.com/jitsi/jitsi-videobridge/pull/1738 and this https://github.com/jitsi/jitsi-videobridge/pull/1736 that means devs plans to get rid of JVB_OPTS

Expected Behavior

REST API should be enabled after updated if it was enabled before update.

Possible Solution

I don’t know.

Steps to reproduce

apt update && apt upgrade -y
reboot
