It seems that the DEB833 format is preferable to the tradinalal
one line format for sources.list and so I thought it a good idea
adopt it before an Excalibur upgrade. Here is what I tried;

Enabled: yes # yes is detault. If yes, this line is optional
Types: deb # choose deb or deb-src
URIs: http://deb.devuan.org/devuan # the base of archive
Suites: excalibur # path of suite relative to URI
Components: main contrib non-free non-free-firmware # sections

Enabled: yes
Types: deb
URIs: http://deb.devuan.org
Suites: excalbur-security
Components: main contrib non-free non-free-firmware

Enabled: yes
Types: deb
URIs: http://deb.devuan.org
Suites: excalbur-updates
Components: main contrib non-free non-free-firmware

Enabled: yes
Types: deb
URIs: http://deb.devuan.org
Suites: excalbur-proposed
Components: main contrib non-free non-free-firmware

Enabled: yes
Types: deb
URIs: http://deb.devuan.org
Suites: excalbur-backports
Components: main contrib non-free non-free-firmware

Unfortunately, none of the key terms were recognized.
Also I did not know what to do with the old /merged, as
in deb http://deb.devuan.org/merged.

Why wouldn't Devuan Daedalus apt accept the DEV822 format?
