[OSGeoLive] adding a repository when build ISO (plain text)

[Geo Qs]

[oops, resending as plain text]

Greetings,

First, thank you to the OSGeoLive team, we are an NGO that's been been happily and gratefully using your project for a few years by installing it on an offline machine.

Recently we're trying to customize the latest ISO according to https://wiki.osgeo.org/wiki/Live_GIS_Build but are running into some issues. We've never built or customized an ISO before, so please forgive us if these are simple questions.

Thank you for your time and any ideas or suggestions you might have! If there is other information we should include, please just let us know.

(Environment - Lubuntu 18.04 in Virtual Machine Manager 2.2.1)

Question 1

Using the command in the wiki:
sudo ./build_chroot.sh release i386 2>&1 | tee /var/log/osgeolive/chroot-build.log
When executing the build script, these error messages occurred:

Warning: apt-key output should not be parsed (stdout is not a terminal)
Executing: /tmp/apt-key-gpghome.utvHzB8R72/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys FADA29F7

Question 2

We already made custom iso file that removed some packages and adding packages we want, but we can't add pgadmin4 and postgresql-11. We added postgresql repository on ‘/home/user/gisvm/source.list.d/osgeolive.list’ file (see below). But it seems like that code is skipped. We also trying adding it on ‘/home/user/gisvm/bin/setup.sh’. So how we can add the repository?

#Postgresql
deb http://apt.postgresql.org/pub/repos/apt bionic-pgdg main
#OSGeoLive Release ppa
deb http://ppa.launchpad.net/osgeolive/release-13.0/ubuntu bionic main
#deb-src http://ppa.launchpad.net/osgeolive/release-13.0/ubuntu bionic main
