Thank you for your report.
I need more information to investigate it.
Specifically:
1) I need to know which specific package you observed this problem with
during an upgrade.
2) I need you to send me the snapshot in
/var/lib/apt/listchanges-snapshots corresponding to the apt run in which
you observed the issue. Please upload it to a file sharing site and send
me the link (privately, not in the ticket). I'll let you know when I've
downloaded it so you can remove the uploaded copy.
Thank you,
Jonathan Kamens
