Yes it did

I stumbled on the reason for my not getting a release file. The
line in my sources.list was

deb http://deb.devuan.org/merged daedalas main non-free contrib

I changed it to

deb http://deb.devuan.org/merged daedalas main

and the update/upgrade worked. I was then able restore the non-free
and contrib and install chromium.
