[Bug 1832687] [NEW] apt-listchanges doesn't work on Ubuntu 19.04

[anatoly techtonik]

Public bug reported:

I've got apt-listchanges installed with the following config:

$ cat /etc/apt/listchanges.conf 
[apt]
frontend=pager
which=news
email_address=root
email_format=text
confirm=1
headers=false
reverse=false
save_seen=/var/lib/apt/listchanges.db

But running `sudo apt-get upgrade` doesn't show any changelogs, the
prompt contains the standard message:

83 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 296 MB of archives.
After this operation, 4.403 kB of additional disk space will be used.
Do you want to continue? [Y/n]

Get:2 http://by.archive.ubuntu.com/ubuntu disco-updates/main amd64 libsystemd0 amd64 240-6ubuntu5.1 [244 kB]     

After which the installation starts immediately.
