The installation stops when a symlink is created. - bbb-html5.service

[kovabor]

Dear All,

I'm trying to install bbb 3.0 apha 3 on ubuntu 22.04.4 with the following command:

wget -qO- https://raw.githubusercontent.com/bigbluebutton/bbb-install/v3.0.x-release/bbb-install.sh | bash -s -- -g -v jammy-300 -s xyz.yxz.hu -e info@*.hu

but so far it always stops at the following line:

Adding bbb-html5.service to autostart using systemd
Created symlink /etc/systemd/system/multiuser.target.wants/bbb-html5.service -> /lib/systemd/system/bbb-html5.service.
Created symlink /etc/systemd/system/bigbluebutton.target.wants/bbb-html5.service -> /lib/systemd/system/bbb-html5.service.

When I stop and restart the server, the page says

"Welcome to BigBlueButton!"

so something is working fine, but the greenlight doesn't install.

Thanks if you can help.
Gábor

I've realised in the meantime that it can't communicate because it has 'http://' instead of 'https', and that's where my address is pointing, the ports are open. how do I set the installer to set itself to 'https'?

freeswitch won't start, probably because of this (ports open)

Hi @kovabor
https would be set in /etc/bigbluebutton/bbb-web.properties

Please share your full logs from bbb-install next time you give it a try if you hit an issue.
The FreeSWITCH ports messages still need a bit of tweaking in the later alphas, they are not very trustworthy right now

[kovabor]

Hi @antobinary

Yes, I've already changed it there and it caused further problems, but I'll check again (in case I didn't change it in this file.)

At the moment I'm thinking about the reverse proxy, as it says it's no good (I read this later, although it's in the description)

"TCP port 80 and 443 are not in use by another web server or reverse proxy"

On the reverse proxy only port 80 ls 443 passes through, but that's probably the problem.

Thanks anyway. i'll get back to you.

@kovabor hey

I have the same problem as you now.
How did you fix this?
My uwf ports are open.

[kovabor]

Hi,

Unfortunately I couldn't solve it yet, I gave up a bit :)

I've installed it in a fully open domain, but it didn't make any difference.

I have installed the new version of the old one, but it still fails.
I installed greenlight in vain, but I got nothing worthwhile.
I will try again soon.

It would be nice to have a simple version of this that doesn't need to be installed like this.

I have a suspicion that when installing bbb-html5 the IP address is checked
http://169.254.169.254/latest/meta-data/public-ipv4

but this service is not running and I suspect that it creates a process stop

`local external_ip
