Getting sudo apt update to work on Raspberry Pi Zero W with Raspbian Trixie (Jan 26)

PS: Please use a power backup next time instead of raw-dogging life.

Preface

Right after first boot, tried running sudo apt update but it kept breaking with the error:

E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/raspbian.raspberrypi.com_raspbian_dists_trixie_main_binary-armhf_Packages (1)

Forget everything about dpkg backups and stuff... rebuild the dpkg cache.

sudo rm /var/lib/dpkg/status
sudo dpkg --clear-avail
sudo dpkg --configure -a
sudo rm -rf /var/lib/apt/lists/*
sudo apt update

Preface

So after killing my Pi Zero W and wrestling with the environment way too many times I have now acquired and Pi Zero 2 W... and life has never been better.

Tailscale

As for the Tailscale part, I have the thing figured out pretty well on Pi Zero W. The issues I get on Zero W are just not there in Zero 2 W.

To install Taiscale on Zero 2 W, simply do:

curl -fsSL https://tailscale.com/install.sh | sh

Cuz auto-login on Gnome without a display just doesn't work fsr...

sudo nano /etc/default/grub

Update the GRUB_CMDLINE_LINUX_DEFAULT variable in this file to have one of the display connectors always active.

ls /sys/class/drm/ # shows a list of available display connectors prefixed with 'card-'

To unlock your keyring from an SSH session, you can use the gnome-keyring-daemon command with the appropriate arguments. A convenient way to do this is to add a function to your bash profile that prompts for the password and executes the command.

You can add a function to your ~/.bashrc file to manually unlock the keyring from the command line when needed.

1. Edit your ~/.bashrc file using a text editor like nano or vim:

nano ~/.bashrc

2. Add the following function to the end of the file:

To make the change persistent, create a file named /etc/systemd/system/battery-charge-threshold.service with the following content:

[Unit]
Description=Set the battery charge threshold
After=multi-user.target

[Service]
Type=oneshot
ExecStart=/usr/bin/bash -c 'echo 80 > /sys/class/power_supply/BAT0/charge_control_end_threshold'

1. Download your .mp4 file in ~/videos/mybg.mp4.
2. Install mpv and mpvpaper.
3. Add this to niri configs

layer-rule {
    match namespace="^mpvpaper$"
    place-within-backdrop true
}

Waveshare UPS Hat (C)

How to setup Waveshare UPS Hat (C) for RPi Zero 2W?

This is relatively easy. For me it was just plug-and-play. Just follow the "How to use?" guide on their wiki: https://www.waveshare.com/wiki/UPS_HAT_(C)

1. Enable I2C from raspi-conifg menu (sudo raspi-config)
2. sudo reboot
3. Install the official library and sample code:

sudo apt-get install p7zip

To use niri as your wayland compositor, and ditch X11, do this:

1. Create /etc/sddm.conf.d/wayland.conf
