Did you read the live build manual? You downloaded a package but its the keyring file inside that live build requires. I am on holidays and don't have access to my main computer with everything on it to tell you exactly how I used to do it. If you had read the manual, like I suggested, you would have it all sorted by now.
Read this https://live-team.pages.debian.net/live-manual/html/live-manual/customizing-package-installation.en.html#customizing-package-installation 8.1.5 Additional repositories You may add more repositories, broadening your package choices beyond what is available in your target distribution. These may be, for example, for backports, experimental or custom packages. To configure additional repositories, create config/archives/your-repository.list.chroot, and/or config/archives/your-repository.list.binary files. As with the --mirror-* options, these govern the repositories used in the *chroot* stage when building the image, and in the *binary* stage, i.e. for use when running the live system. For example, config/archives/live.list.chroot allows you to install packages from the debian-live snapshot repository at live system build time. deb http://debian-live.alioth.debian.org/ sid-snapshots main contrib non-free If you add the same line to config/archives/live.list.binary, the repository will be added to your live system's /etc/apt/sources.list.d/ directory. If such files exist, they will be picked up automatically. *You should also put the ASCII-armored GPG key used to sign the repository into config/archives/your-repository.key.{binary,chroot} files. (highlighting by me)* Should you need custom APT pinning, such APT preferences snippets can be placed in config/archives/your-repository.pref.{binary,chroot} files and will be automatically added to your live system's /etc/apt/preferences.d/ directory. Similarly, if you need custom APT_AUTH.CONF(5) authentication configuration, this can be placed in config/archives/your-repository.auth.{binary,chroot} files and will be automatically added to your live system's /etc/apt/auth.conf.d/ directory On Sat, 13 Jan 2024 at 17:48, Andrea - <andrea.carbonar...@gmail.com> wrote: > I went here: > > https://wiki.trinitydesktop.org/Debian_Trinity_Repository_Installation_Instructions#TDE_R14.x.y_series > > I installed the file: trinity-keyring.deb > But the problem remains > ------------------- > I used to build TDE in Live Build but haven't done so for a couple of > years.
