How to fix N: Skipping acquire of configured file 'main/binary-i386/Packages' as repository doesn't have the component in APT

Run this command to see all enabled architectures:

dpkg --print-architectures

You should see 'amd64' (64-bit). If you see 'i386' listed separately or in foreign architectures, that's why APT is looking for 32-bit packages.

Look at the full apt update output to find the repository URL mentioned in the warning. For example:

N: Skipping acquire of configured file 'main/binary-i386/Packages' as repository 'http://repository.spotify.com stable InRelease' doesn't have the component

This tells you the Spotify repository doesn't have i386 packages.

The recommended fix is to specify that the repository only supports amd64 architecture. Find the source file (usually in /etc/apt/sources.list.d/) and add [arch=amd64]:

Before:

deb http://repository.spotify.com stable non-free

After:

deb [arch=amd64] http://repository.spotify.com stable non-free

Edit the file with:

sudo nano /etc/apt/sources.list.d/spotify.list

Save and exit (Ctrl+O, Enter, Ctrl+X).

Run apt update to verify the warning is gone:

sudo apt update

If you've fixed all repositories, you should no longer see the 'Skipping acquire' warnings.

If you don't need 32-bit package support, you can remove the i386 architecture entirely:

sudo dpkg --remove-architecture i386
sudo apt update

Use this option only if you're certain no installed applications require 32-bit libraries. Check with:

sudo apt list --installed | grep :i386

If nothing is listed, it's safe to remove.
