Ubuntu 22.04.1: apt-offline get --bundle option not working

--bundle file.zip option is not working. What am I doing wrong?

Ubuntu 22.04.1

~ $ apt-offline set --update --upgrade offline.sig
~ $ apt-offline get offline.sig --bundle offline.zip

Downloaded data to offline.zip

As you can see --bundle offline.zip doesn't really download anything other PGP signature.

-d DIRECTORY option works fine though.

Ran into the exact same issue. Was able to resolve by editing my threading.py file (/usr/lib/python3.10/threading.py), finding every time warnings.warn() function was called, and commenting these lines out.

Not the proper fix, but it did get the proper download process started for me.
