Zero 3W update failed

#1

Fresh installed OS, bullseye. Unable to update: fail over rsetup or with apt. No pubkey, the repository not signed.

#2

The reason is that backports are no longer available for bullseye. The rough process I used was:

Edit /etc/apt/sources.list - change bullseye to bookworm.

Do the same for:
/etc/apt/sources.list.d/bullseye-backports.list
/etc/apt/sources.list.d/bullseye-security.list
/etc/apt/sources.list.d/bullseye-updates.list

Update keys: sudo apt install debian-keyring debian-archive-keyring

Hold back wifi module and disable the repo (there is no bookworm modules provided):
cat << ‘EOF’ | sudo tee /etc/apt/preferences.d/radxa-wifi
Package: aic8800-dkms linux-firmware-rockchip
Pin: release o=radxa-repo.github.io
Pin-Priority: 1001
EOF
sudo mv /etc/apt/sources.list.d/radxa.list{,.disabled}
sudo mv /etc/apt/sources.list.d/radxa-rockchip.list{,.disabled}

Then:

sudo apt update
sudo apt upgrade --without-new-pkgs
sudo apt full-upgrade
sudo apt autoremove --purge
sudo reboot

You’ll need to reenter the WiFi passphrase after updating.

Hope that helps.

Package debian-keyring is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source.

#4

Is it because the two radxa files in /etc/apt/sources.list.d need to be renamed to .disabled
