In previous versions you could remove the Amazon app via the Ubuntu Software application, under "uncategorised". But in 16.04 I can't find it there, so how do I get rid of it.
Thank you please.
Don't worry you can remove/dissable it from command line.
Try this first,
gsettings set com.canonical.Unity.Lenses disabled-scopes "['more_suggestions-amazon.scope', 'more_suggestions-u1ms.scope', 'more_suggestions-populartracks.scope', 'music-musicstore.scope', 'more_suggestions-ebay.scope', 'more_suggestions-ubuntushop.scope', 'more_suggestions-skimlinks.scope']"
if above not works for you , try followng,
sudo apt-get remove unity-webapps-common
