OS Debian x64. During $sudo debuild -tc I've got the error: Now signing changes and any dsc files... signfile dsc libmfp2-canon_0.1.dsc Thierry HUCHARD thierry@ordissimo.com gpg: skiped "Thierry HUCHARD thierry@ordissimo.com": No secret key gpg: /tmp/debsign.3bwIyzv9/libmfp2-canon_0.1.dsc: clear-sign failed: No secret key debsign: gpg error occurred! Aborting.... debuild: fatal error at line 1112: running debsign failed

How can I add the signfile?

Hi @pavelkq , This is my key, it is only necessary if you broadcast the binaries. To avoid this message being used: sudo debuild -i -us -uc -b

pavelkq commented 3 years ago

Yes - It works! But SANE can't see my CANON scanner(( Just scangearmp works well.

Ok, it's been a while since I've updated the code for this project. New commit I've added what's needed to support version 4.10. Can you rebuild it and tell me if it's ok?

ThierryHFR commented 3 years ago

These changes add support for sources, resolution and paper size.

I've just repeated the installation process by steps, but haven't got result:

$ sudo sane-find-scanner 

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

What is your version of debian?

pavelkq commented 3 years ago

It's debian 10.8 (x86-64), kernel 4.19.0-14-amd64

Hi @pavelkq , Can you test with my version of scangearmp2, it contains the backend for Sane ? https://github.com/Ordissimo/scangearmp2/releases/tag/v4.11

sudo apt purge libmfp2-canon scangermp2
sudo apt install  ./scangearmp2_4.11_amd64.deb
pavelkq commented 3 years ago

I've done it. And I've found the interesting case. I entered $sudo scanimage -Lv and remembered that scanner had not been turned on. I turned it on immediately and it was found. I tried to start the Simple scanner program but it couldn't see the scanner. I entered $sudo scanimage -Lv again and it didn't work now.

I repeated the steps and everything repeated. What does it mean?

By the way on another linux distributive (Live CD AltLinux based on MandrakeLinux) this scanner works well.

ThierryHFR commented 3 years ago

Thanks for the test: Can you edit the file /etc/sane.d/dll.conf and comment on the line containing : pixma in # pixma

then test again, turn off your scanner and turn it back on.

pavelkq commented 3 years ago

Thank you for helping! I did it. Scanner stopped work. And it din't depend on turning on. Then I returned dll.conf in first state. But scanner doesn't work yet in any case.

Ok, from what I see it is your version of sane that is corrupt! I propose you to build the binary packages from the latest version of sane-backends. The sane project proposes binary for Ubuntu but not for debian (the lauchpad is restrictive). https://launchpad.net/~sane-project Your device was added 2 years ago and is supported by the PIXMA driver : This commit

sudo apt-get install build-essential fakeroot devscripts haskell-debian-utils
dget https://launchpad.net/~sane-project/+archive/ubuntu/sane-release/+sourcefiles/sane-backends/1.0.32-bionic0/sane-backends_1.0.32-bionic0.dsc

pavelkq commented 3 years ago

I had security issues while running the dget command. Then I tried to install the sane-beckends in other ways. But nothing happened. Then I decided to upgrade to bullseye version (it contains 1.0.31 version of sane). Now my scanner works fine! Thank you!

Great!
