file dict.db is in line with CC-CEDIT as of 28/01/2026

place dict.db and clipboard_lookup.py in chosen (the same) location; place chinese-lookup-wrapper.sh in ~/bin (create ~/bin if it doesn't already exist);

Ubuntu/Ubuntu-Studio wayland tested (should work on most debian based distros)

install any missing dependencies if prompted:

Database and data processing

python3-sqlite3 # Usually pre-installed

Pinyin tone mark generation

python3-pypinyin

Alternative (if using venv):

pip install pypinyin

For Wayland (Ubuntu Studio default):

wl-clipboard # Clipboard access python3-notify2 # Desktop notifications

For X11 systems (non-Wayland):

xclip # Clipboard access python3-notify2 # Desktop notifications

DBus support (usually pre-installed)

libnotify-bin # Notification daemon dbus # Message bus system

sudo apt install python3-pypinyin xclip python3-notify2 libnotify-bin

(for troubleshooting - optional) python3-dbus # DBus Python bindings gir1.2-gtk-3.0 # GTK/GObject introspection (for alternative clipboard)

Most Ubuntu/Debian systems already have python3-sqlite3, dbus, and libnotify-bin installed by default.
