Suggestion: in the release notes, advise the user to disable aptlist-changes

[LinuxOnTheDesktop]

I discover from the upgrade log that apt-listchanges very much enlarged that log. The programme will have slowed down the upgrade too. It is possible also that the program is responsible for a Cinnamon crash that I had mid-way through one upgrade. Hence my titular suggestion.

I think that the following will suffice for the disabling.

In /etc/apt/listchanges.conf, set the two 'frontend' entries to none - but make a note of what the previous values were, so that you can restore them after the upgrade.
