Installing WebMeetings from the Repositories

So I’m just starting off trying to install webmeetings, and I want everything to be based on repositories moving forward.
I’ve added the repositories into my sources.list.d directory and this is the output I get when trying to update:

This is I have these same repositories on other servers (all made from the same VM template) and have imported the keys just fine on them. Any ideas?

Thanks

P.S. Sorry for all the edits, I’m still getting use to this interface…

Hello Robert,

don’t worry about the edit, we won’t charge extra because of them ;-)

Btw. you can also wrap everything into block quotes in Markdown, for better readability I did so in your posting.

Are you sure you imported to correct key? what happens if you execute

curl https://<username>:<password>@download.kopano.io/supported/core:/final/Ubuntu_16.04/Release.key | apt-key add -

again?

Aah, so I see… 3 backquotes…

So I was able to run the command and now apt update works fine:

zarafa-meetings:~# curl https://USERNAME:PASSWORD@download.kopano.io/supported/core:/final/Ubuntu_16.04/Release.key | apt-key add -
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  3102  100  3102    0     0    507      0  0:00:06  0:00:06 --:--:--   675
OK

I’m betting the problem is that a username/password is required to get the key so the basic apt-key command won’t work.

Thanks
Bob
