During the recent upgrade I got a Python syntax warning,
probably it was caused by the Python 3.12 transition.
Preparing to unpack .../archives/nyx_2.1.0-3_all.deb ...
Unpacking nyx (2.1.0-3) over (2.1.0-2.3) ...
Setting up nyx (2.1.0-3) ...
/usr/lib/python3/dist-packages/nyx/curses.py:118: SyntaxWarning: invalid escape sequence '\['
ANSI_RE = re.compile('\x1B\[([0-9;]+)m')
Still happening with Python 3.13.5 and nyx 2.1.0-3.
