Your source entries are wrong.
Change them from canonical to ubuntu

Yours show

'http://archive.canonical.com/ubuntu

should be

'http://archive.ubuntu.com/ubuntu

I don't think the canonical archive repo has anything other than Partner.
And Partner is basically obsolete, since the last useful package it provided was adobe-flashplugin.


EDIT:
You might post your sources.list file as you might already have the proper entry and only need to remove the referenced canonical entry(ies?)
Easiest to just copy the output from

cat /etc/apt/sources.list

and post it.

You said should be

'http://archive.ubuntu.com/ubuntu

and see at :

cat /etc/apt/sources.list

Well, I'll try.

Soo I'll change canonical to ubuntu.com

The conclusion was :
The repository 'http://archive.ubuntu.com focal Release' does not have a Release file.

E: The repository 'http://archive.ubuntu.com focal Release' does not have a Release file.

But alwasy success update using Desktop Version, Gnome Version : Software Updater.
Using Terminal console, yup, it : E: The repository 'http://archive.ubuntu.com focal Release' does not have a Release file.

You never posted the output showing the contents of your changed sources.list file to confirm it was good... In that case, how about this.

What happens if you try this as your /etc/apt/sources.list file?
