Comment 1 for bug 1885298

On Launchpad side, this error message is raised at nascentuploadfile.py, while using apt_inst.DebFile to read deb file information:

deb_file = apt_inst.DebFile(self.filepath)
control_file = deb_file.control.extractdata("control")
control_lines = apt_pkg.TagSection(control_file, bytes=True)

I've got the package, but couldn't reproduce locally the error, with the same lines (using LXD with both Bionic and Xenial distros).

A MP was accepted to add the exception message to the logs, in the hope of getting more useful information on what is going on.
