Hi,
I try to install Zammad on Debian 9 as described here:
https://docs.zammad.org/en/latest/install-debian.html
As a result of the instructions my sources.list looks like this:
deb https://dl.packager.io/srv/deb/zammad/zammad/stable/debian 9 main
Wen I try to do “apt update” I get:
root@ticket:~# apt update
Ign:1 https://dl.packager.io/srv/deb/zammad/zammad/stable/debian 9 InRelease
Err:2 https://dl.packager.io/srv/deb/zammad/zammad/stable/debian 9 Release
Received HTTP code 403 from proxy after CONNECT
Ign:3 http://ftp.de.debian.org/debian stretch InRelease
Hit:4 http://security.debian.org/debian-security stretch/updates InRelease
Hit:5 http://ftp.de.debian.org/debian stretch-updates InRelease
Hit:6 http://ftp.de.debian.org/debian stretch Release
Reading package lists... Done
E: The repository 'https://dl.packager.io/srv/deb/zammad/zammad/stable/debian 9 Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
Is there some where a working APT source?
TIA
