Repositories configuration
Most of servers you can use same repositories set, for Debian 8:
deb http://ftp.us.debian.org/debian/ jessie main contrib non-free
deb http://ftp.us.debian.org/debian/ jessie-updates main
deb http://security.debian.org/ jessie/updates main
deb http://pkg.yeti-switch.org/debian/jessie 1.7 main
And for Debian 9:
deb http://ftp.us.debian.org/debian/ stretch main contrib non-free
deb http://ftp.us.debian.org/debian/ stretch-updates main
deb http://security.debian.org/ stretch/updates main
deb http://pkg.yeti-switch.org/debian/stretch 1.7 main
System repositories can be changed by editing of file: /etc/apt/sources.list. Since we use our own package repository you have add our key to trusted. There is two ways to do it:
# apt-key adv --keyserver keys.gnupg.net --recv-key 9CEBFFC569A832B6
or
# wget http://pkg.yeti-switch.org/key.gpg -O - | apt-key add -
Warning
Since yeti-web version 1.6.0 it is important to install Postgresql from PGDG repository.
On your datadabase hosts(routing and CDR) you should add additional PGDG repository:
deb http://apt.postgresql.org/pub/repos/apt/ jessie-pgdg main
Or for Debian 9:
deb http://apt.postgresql.org/pub/repos/apt/ stretch-pgdg main
You can add PGDG repository key to trusted using command:
# wget https://www.postgresql.org/media/keys/ACCC4CF8.asc -O - | apt-key add -
