Normally I run the update process several times a week with the command

Correct.
This morning this resulted in the error

The following partially installed packages will be configured:
    brscan4
As I think at least one other person has noted, this does not appear to
be available in the Debian archives, at least not as far as I've managed
to determine.
That's correct. It is pat of the Brother Laser Printer driver package.
No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
E: Can't find a source to download version '0.4.8-1' of 'brscan4:amd64'
After unpacking 0 B will be used.
E: Can't find a source to download version '0.4.8-1' of 'brscan4:amd64'
To my eye, this looks as if something is telling apt that version
0.4.8-1 is available somewhere, and the upgrade session is deciding that
it needs to install that version, but then none of the configured
sources include that version (and it's not already cached locally).

What do

$ apt-cache policy brscan4
$ apt-cache rdepends brscan4

say?

Thank you for your reply.

comp@AbNormal:~$ apt-cache policy brscan4
brscan4:
  Installed: 0.4.8-1
  Candidate: 0.4.8-1
  Version table:
 *** 0.4.8-1 100
        100 /var/lib/dpkg/status
comp@AbNormal:~$ apt-cache rdepends
E: No packages found

Suggestions?
