N: Skipping acquire of configured file 'main/binary-i386/Packages' as repository 'http://apt.postgresql.org/pub/repos/apt focal-pgdg InRelease' doesn't support architecture 'i386'

I have no idea how to solve this! can anybody help me solve this please? Thanks in advance!

    This is not answered in the other question for me. – geneorama Dec 18 '20 at 19:04

The definition for your apt.postgresql.org repo is defined in one of two possible places. Let's find it...

In terminal...

sudo grep -i postgresql /etc/apt/sources.list


sudo grep -i postgresql /etc/apt/sources.list.d/*.list

You'll get a hit on one of the above commands.

Let's edit the file...

sudo -H gedit /etc/apt/sources.list (ignore any warning messages)


sudo -H gedit /etc/apt/sources.list.d/found_filename.list (ignore any warning messages)

Find the line that starts with...

deb https://blah blah blah

And change it to...

deb [arch=amd64] https://blah blah blah

Save the file and quit the editor.

Now sudo apt-get update and sudo apt-get upgrade will run without the noise.

    I had the same issue with qgis. Changing deb https://qgis.org/debian focal main to deb [arch=amd64] https://qgis.org/debian focal main solved my issue with "skipping acquire of configured file..." – geneorama Dec 18 '20 at 19:06
