This error is suggesting that your sources.list configuration is still wrong.

I always follow the documentation on apt.postgresql.org which in a web browser will redirect to Postgres wiki at https://wiki.postgresql.org/wiki/Apt

Remove all your existing postgresql apt sources and follow the quickstart there. You need a slight modification to set the Debian codename for the setup script.

This is part of what I use in my automation to install Postgres from the upstream repository:

- - - - 8< - - - -

# Use tzdata package to get the debian release codename
debian_codename=$(dpkg --status tzdata | grep Provides | cut -f2 -d'-')

postgresql_version="16"

# Install postgresql-common
apt install -y postgresql-common

# Enable data checksums for new clusters:
sed -i "s/#initdb_options = ''/initdb_options = '--data-checksums'/" /etc/postgresql-common/createcluster.conf

# Configure postgresql repository
/usr/share/postgresql-common/pgdg/apt.postgresql.org.sh -y "${debian_codename}"

# Install postgresql
apt update
apt install -y "postgresql-${postgresql_version}"

- - - - 8< - - - -

That error suggests you haven’t installed their repository gpg key correctly. Unfortunately their docs appear to be a bit outdated and suggest using apt-key which is either deprecated or no longer working.

https://wiki.x2go.org/doku.php/wiki:repositories:debian

sudo gpg --keyserver hkp://keyserver.ubuntu.com:80 --no-default-keyring --keyring /etc/apt/keyrings/x2go.gpg --recv-keys E1F958385BFE2B6E

It should download the gpg key into /etc/apt/keyrings. I coped the gpg fingerprint from their docs but I’m not sure it’s in the correct format. Try and see if it works.

Then update the first part of each line in the x2go.sources file to use the gpg key:

deb [signed-by=/etc/apt/keyrings/x2go.gpg]
