After checking /etc/apt/sources.list.d (which was empty), I tried
adding ppa:sane-project/sane-release, with very similar 404 error
and "... disabled by default" messages.

$ sudo add-apt-repository ppa:sane-project/sane-release

However this time it did add a file to /etc/apt/sources.list.d:

$ ll /etc/apt/sources.list.d
total 12
drwxr-xr-x 2 root root 4096 May 21 14:08 ./
drwxr-xr-x 7 root root 4096 May 21 10:42 ../
-rw-r--r-- 1 root root  154 May 21 14:09 sane-project-ubuntu-sane-release-bionic.list

$ cat /etc/apt/sources.list.d/sane-*
deb http://ppa.launchpad.net/sane-project/sane-release/ubuntu bionic main
# deb-src http://ppa.launchpad.net/sane-project/sane-release/ubuntu bionic main

Does this mean that it worked, despite the error messages?
