[Desktop-packages] [Bug 1879024] Re: Error message : "Failed to scan - unable to connect to scanner" when using simple-scan
Have exactly same error with Brother MFS-L8900CDW
Upgraded from 18.04.5 - was working well before upgrade.

Title:
Error message : "Failed to scan - unable to connect to scanner" when
using simple-scan
Status in simple-scan package in Ubuntu:
Confirmed
Bug description:
1) System and program information:
I am using Ubuntu 20.04 LTS and am trying to use the brother printer/scanner
combo MFC-J5910DW in order to scan documents with simple-scan:
simple-scan:
Installed: 3.36.0-0ubuntu1
Candidate: 3.36.0-0ubuntu1
Version table:
*** 3.36.0-0ubuntu1 500
500 http://de.archive.ubuntu.com/ubuntu focal/main amd64 Packages
100 /var/lib/dpkg/status
2) Description of what I did and what happened:
I downloaded and installed the newest scanner driver deb-packages (2 of them)
from the official brother web-page and installed them using
$ sudo apt-get install ./'sannerdirverfilename'.deb
and there was no error message. So I also installed simple-scan from
the Ubuntu repository using:
$ sudo apt-get install simple-scan
This also worked just fine. But when I now try to use simple-scan, it
doesn't work. I call the program from the terminal command line:
$ simple scan
and it opens an interactive window, searches for a scanner and finds
the brother scanner. But when I then hit the 'scan' button, I get the
error message
"Failed to scan - unable to connect to scanner"
3) Error Log for simple-scan:
So I used simple-scan with the debug option, and here is the log-file:
