➜  ~ sudo apt-get update

Runing though 80 port - no data:

Looks like NVIDIA has updated its signing keys as of April 27, 2022. You can follow these instructions to update your system with the new ones.

The recommended method is to use a helper package to automatically install the keys. To install the helper package (and the keys), run the following commands:

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-keyring_1.0-1_all.deb
sudo dpkg -i cuda-keyring_1.0-1_all.deb

Alternatively, you can install the key manually by using the following commands (not the recommended method):

sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/3bf863cc.pub

apt-key now seems to be deprecated, I have created a script that will detect and get the missing keys, you can get it here.

#!/bin/sh -e
tmp="$(mktemp)"
sudo apt-get update 2>&1 | sed -En 's/.*NO_PUBKEY ([[:xdigit:]]+).*/\1/p' | sort -u > "${tmp}"
cat "${tmp}" | xargs sudo gpg --keyserver "hkps://keyserver.ubuntu.com:443" --recv-keys  # to /usr/share/keyrings/*
cat "${tmp}" | xargs -L 1 sh -c 'sudo gpg --yes --output "/etc/apt/trusted.gpg.d/$1.gpg" --export "$1"' sh  # to /etc/apt/trusted.gpg.d/*
rm "${tmp}"

In addition to the other answer with Nvidia instructions, run the following commands to fix your seafile repository.

If the first command fixes the problem, you can skip the second command.

sudo wget https://linux-clients.seafile.com/seafile.asc -O /usr/share/keyrings/seafile-keyring.asc
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/seafile-keyring.asc] https://linux-clients.seafile.com/seafile-deb/$(lsb_release -cs)/ stable main" | sudo tee /etc/apt/sources.list.d/seafile.list > /dev/null

The official instructions can be found here.

Just run

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A4B469963BF863CC

This will download the missing key from the keyserver repository.
