Comment 22 for bug 1730627

> I'm seeing this bug on Ubuntu bionic 18.04 with dpkg v.1.19.0.5ubuntu2.

no, you're not. The message may look similar but it is not the same.

> $ sudo dpkg -i <file>.deb

hm, i don't have the '<file>.deb' anywhere on my system ;-P

Obfuscating what deb you're have a problem with isn't helpful as the problem very well may be with that deb, and makes it impossible for anyone to reproduce your problem.
