I've also found this, I've already tried a dnf clean and rpm --rebuilddb but without luck. is there anything I can do to help the triage?

I have the same problem

Basically, running "sudo dnf install naut[TAB]" makes dnf hangs, so I have to stroke ctrl-c to get the prompt control back.

Seeing at the bash-completion file, I saw the Python code responsible of autocompleting packages and tried to execute that snippet by hand:

$ python3 -c "import sys; from dnf.cli import completion_helper as ch;ch.main(sys.argv[1:])" install naut -d 0 -q -C
Importing GPG key 0x429476B4:
 Userid     : "Fedora 29 (29) <fedora-29>"
 Fingerprint: 5A03 B4DD 8254 ECA0 2FDA 1637 A20A A56B 4294 76B4
 From       : /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-29-x86_64
Is this ok [y/N]:

So this prompt is not letting dnf to show the completions, even by responding Y here, the subsequent execution of the completion command ask to import this key again.
