It turns out that this is caused by installing the package
apt-listchanges. I had installed this because I was interested in
command-line access to package changelogs.

Once you know it's happening it's easy enough to open the details pane
in the updater, click in it, and press "q"; the changelog display will
end and the update processing will continue.

Alternatively you can uninstall apt-listchanges.

A further option is to rename this:
    /etc/apt/apt.conf.d/20listchanges
to this:
    /etc/apt/apt.conf.d/20listchanges.disabled

I haven't tried it, but removing /etc/apt/apt.conf.d/20listchanges
entirely might also work. The specific filename is not relevant, but the
extension ".disabled" extension is.

The file /etc/apt/apt.conf.d/20listchanges appears to be installed with
apt, not with apt-listchanges. Removing apt-listchanges will rename the
file to 20listchanges.disabled, and installing apt-listchanges will
change the file back to 20listchanges, but if you remove the file, then
installing apt-listchanges will not recreate it.

Thank you to Colin Law, Tommy Trussell and especially Oliver Grawert for
their help on this one.

Regards, K.
