When I run sudo apt-get update in the terminal the following error messages are shown:

N: Skipping acquire of configured file 'main/binary-i386/Packages' as repository 'https://packages.microsoft.com/repos/vscode stable InRelease' doesn't support architecture 'i386'

I tried following Scott Stensland's answer this way:

1. cd /etc/apt/sources.list.d


2. 
   

   ls gives:

   
   
   

   google-chrome.list 
   nilarimogard-ubuntu- webupd8-xenial.list
   google-chrome.list.save 
   nilarimogard-ubuntu-webupd8-xenial.list.save
   graphics-drivers-ubuntu-ppa-xenial.list 
   vscode.list
   vscode.list.save
   graphics-drivers-ubuntu-ppa-xenial.list.save 
   linuxuprising-ubuntu-java-xenial.list 
   webupd8team-ubuntu-java-xenial.list
   linuxuprising-ubuntu-java-xenial.list.save 
   webupd8team-ubuntu-java-xenial.list.save
   

   
   



3. cat vscode.list gives:

### THIS FILE IS AUTOMATICALLY CONFIGURED ###

## You may comment out this entry, but any other modifications may be lost.##

deb [arch=amd64] http://packages.microsoft.com/repos/vscode stable main

It seems that vscode is already limited to 64 bit. What can I do in this situation?
