@netology --

I don't know anything about your app/service but, from what you posted, it looks to me like the vendor has removed support for Debian 9.0 ("Stretch").

I suggest you run this by the vendor…

-- sw

Looks like I found this as a fix

@JohnS_3CX it works now
I followed the answer from 3CX support:

Please try the following:

Modify the following file: /etc/apt/sources.list.d/busylight.list

You can do this using nano as so: nano /etc/apt/sources.list.d/busylight.list

Then, comment out the one line by adding a # symbol in front of it. You should end up with the following contents in the file:

#deb http://kbl.bilisim.me/debian ./

Save it and then use cat /etc/apt/sources.list.d/busylight.list to confirm that the contents is still commented out(with the # symbol). If yes, please try to update 3CX again and let me know what happens.

or manual update by:

Bash:

wget -O - https://downloads.3cx.com/downloads/misc/debianpatches/9/16/0/5/20200619-os-update.sh | bash
