Please move that 90-canonscanner.rules file out of the way and see if
that fixes things. I *think* that invalid rule trigger the cascade of
errors you see.

I don't see the offending file in any of the Devuan/Debian packages so
assume you installed a Canon provided scanner driver. In that case
Canon really should be fixing this up but you could post the file (here
or over at the sane-devel list) so I can take a look.

# FTR, I'm the SANE Project Janitor :-)

Hope this helps,
