Had this exact issue on Fedora 34 as well. Using tracer 0.7.5, and 4.0.13 of python3-dnf-plugin-tracer.

This is also happening in Mageia, see mgabz#28577.

Thank you for the reports guys,
yet another occurrence seems to be reported here
https://bugzilla.redhat.com/show_bug.cgi?id=1958779

I am planning to do some Tracer bugfixing the following week and make a new release.

I was trying to fix this issue several times already and the best
summary I could write was this one

#151 (comment)

It doesn't any sense to me since the problematic line is

    self.args.applications.with_helpers().exclude_types(types).sorted("helper")

which first filters only applications that have non-`None` helper and
only those try to sort, i.e. when sorting there shouldn't be any
`None` values.

Anyway, the issue is real and occurs to many people, so I am reworking
the sorting function and making sure it doesn't traceback when some
helper is `None`. I have no idea what are the problematic applications
and how they will be displayed in the output but I guess everything is
better than a traceback. And maybe it will help us move closer to a
proper solution.
