dnfdragora cryptic error: 'NoneType' object has no attribute 'installed'

I tried to update Fedora 32 and did not realize that my ISP DNS was down. dnfdragora gave the following cryptic backtrace. It doesn't say anything about DNS nor the network. This type of error message brings Fedora Linux closer to parity with Windows NT. ;)

Code:

Error occurred:

g-io-error-quark: GDBus.Error:org.freedesktop.DBus.Python.AttributeError: Traceback (most recent call last):

  File "/usr/lib64/python3.8/site-packages/dbus/service.py", line 711, in _message_cb

    retval = candidate_method(self, *args, **keywords)

  File "/usr/lib/python3.8/site-packages/dnfdaemon/server/__init__.py", line 68, in newFunc

    rc = func(*args, **kwargs)

    value = self.get_packages(pkg_filter, fields)

    pkgs = getattr(self.base.packages, pkg_filter)

AttributeError: 'NoneType' object has no attribute 'installed'

 (36)

On top of that, dnfdragora has a new, additional top menu that pushes the bottom row of buttons off the screen. The window cannot be resized nor scrolled, making the GUI unusable on my laptop display with max resolution of 1366x768.

Can you update via command line?

Code:

sudo dnf --refresh upgrade

Then do it. dnfdragora on Fedora is a bug-ridden crap.

Yes, that is what i am doing now.

Once upon a time, there was rhbz#1257609, so the bug at hand seems even to predate dnfdragora existence (yumex-dnf also used dnfdaemon as its backend).

It amuses me how significant numbers of important bug reports are auto-closed.

"Ooh, shiney new version! We forgot that any bugs existed."
