Fresh install of Lubuntu
Installed updates from synaptic
Installed wine and components from synaptic, upon what I assume is completion it popped this error code.
Is it something I should rush to fix?
This is a known bug:
They suggest running the following command:
sudo chown _apt /var/lib/update-notifier/package-data-downloads/partial/
Give it a try and see if it fixes the issue.
