Kupfer v323: [kupfer.core.plugins]: SyntaxError: '(' was never closed (apt_tools.py, line 14)

[hosiet]

Environment

Kupfer Version: v323
Window Manager: KWin
Desktop Environment: KDE Plasma 5.27.9
Linux Distribution: Debian Sid/Unstable

Actual Behaviour

The following stderr output appears when I open the "preferences" dialog:

INF [kupfer.ui.browser] WindowController: Trying to register <Ctrl>space to spawn kupfer.. success
INF [kupfer.ui.session] SessionClient: Warning: Not able to connect to current desktop session, please Quit before logout to save kupfer's data.
ERR [kupfer.core.plugins]: When loading kupfer.plugin.apt_tools
EXC [kupfer.core.plugins]: SyntaxError: '(' was never closed (apt_tools.py, line 14)
INF [kupfer.core.sources] PeriodicRescanner: Starting new campaign, interval 1 s

Looking at the source code:

kupfer/kupfer/plugin/apt_tools.py

Lines 1 to 18 in 6a53739

	from __future__ import annotations
	__kupfer_name__ = _("APT")
	__kupfer_sources__ = ()
	__kupfer_text_sources__ = ()
	__kupfer_actions__ = (
	"ShowPackageInfo",
	"SearchPackageName",
	"InstallPackage",
	"OpenPackageWebsite",
	"SearchForFile",
	)
	__description__ = _("Interface with the package manager APT")
	__version__ = ""
	__author__ = (
	"Martin Koelewijn <martinkoelewijn@gmail.com>, "
	"Ulrik Sverdrup <ulrik.sverdrup@gmail.com>"
	)

I don't quite understand why there is a such SyntaxError.

Expected Behaviour

No stderr output appears.

Well, there is no error in line 14. I can't reproduce this error.

Please check is your (local) apt_tools.py file is correct. Ale delete all pycache dirs in Kupfer dir.
If you have updated code from repo - maybe merge failed.

[hosiet]

I don't understand this error as well. When executed directly from freshly-cloned repository, this error will occur. I have made sure that no pycache dir is present. See the terminal interaction history below:
