Public bug reported:
On my Ubuntu server, I received the message for quite some time (> 1 year):
"The list of available updates is more than a week old"
I regularly run "apt update", so the message simply isn't true.
After some research, I manage to identify the script
"/usr/lib/update-notifier/apt-check" as the root cause.
When executed with parameter "--human-readable", the following exception is
thrown.
Without "--human-readable", no exception is thrown.
Traceback (most recent call last):
