I unpacked the package brscan2, which seemed to be missing data, as well 
as brscan-skey, which seemed to have all it's data.

I added some of the data (particularly 'Section,' 'Priority') to the 
'control' text file. Unfortunately, before I repackaged it I moved /usr 
into /data. Then I repackaged it.

I did NOT use --force, that is the way the Brother install script is 
written! (I was as surprised as you when I saw this is the output.)

You may not know how to fix this. I wonder though, where were you when I 
first posted (2020-06-22) a need for help to get brscan2 working. (It  
has worked for 10 years on various versions of Ubuntu, as well as 2 
different computers (1 Compaq and 1 Dell) and stopped working when I 
changed hardware to an HP.

Do you lurk on this list and wait for a opportunity to burn someone who 
made a mistake in stead of offering help?

May be if I got real help with this in the first place I wouldn't be in 
this predicament.

If I return the system to the way it was before I removed these files 
manually, will that enable me to remove the package?

My data, or at least most of it, is on a different physical HD.
