I am trying to install trinity for the first time on my stretch system[*],
following the instructions at

I added the Preliminary Stable Builds sources to sources.list.

The GPG key was added OK:


sudo apt-key adv --keyserver --recv-keys F5CFC95C
Executing: /tmp/apt-key-gpghome.STqKpDhXXj/ --keyserver --recv-keys F5CFC95C
gpg: key 96C95152F5CFC95C: public key "QuickBuild Trinity Desktop Environment"
gpg: Total number processed: 1
gpg:               imported: 1


But then:

[HN:apt] sudo apt-get update
Ign:1 stretch InRelease

Hit:2 stretch-updates InRelease

Hit:3 stretch Release

Get:4 stretch/updates InRelease [62.9 kB]

I don't want to install anything that can't be verified. What do I need to do


[*] Anyone who has tried to use the KDE 5 that is included with stretch will
know why I've finally given up on the KDE death-spiral and want to get back to
something that works properly. I would have been here long ago if TDE were an
official part of debian, but KDE 5 is so painful and bug-ridden that I am now
forced to overcome my deep-rooted distrust of software that is not in the
official debian repositories.
