[Bug 1614191] Re: [Blocker] Upgrades are failing with error : Dpkg::Tools::Options::/usr/bin/apt-listchanges::InfoFD should be greater than 2

Feedback

Closing the gnome-shell session and doing a cold reboot solve that problem: the queued packages has been upgraded without getting this error.
I am not closing that report as i'm not sure about a needed fix, or a simple warning comment added into the changelog to help users understanding this issue.
