Nixpkgs: utsushi fails to scan with ES-60W

[thedavidmeister]

Describe the bug

as discussed https://github.com/NixOS/nixpkgs/pull/70160

utsushi/xsane fails to scan

paper is fed into machine, fails to create PDF with cryptic error message "operation was cancelled" (see screenshot in linked thread)

To Reproduce

add to systemPackages both utsushi and xsane (i also have usbutils, sane-backends and sane-frontends, swingsane, skanlite, gnome3.simple-scan for various debugging i've been doing)

add to config

  hardware.sane.enable = true;
  hardware.sane.extraBackends = with pkgs; [
   pkgs.utsushi
  ];
  services.udev.packages = [
   pkgs.utsushi
  ];

point at a recent commit in master

sudo nix-channel --add https://github.com/NixOS/nixpkgs/archive/5078eba3aa90f2ea87dc84ccc96991bc3f386d97.tar.gz nixos
sudo nixos-rebuild switch --upgrade

Expected behavior
A clear and concise description of what you expected to happen.

xsane should be able to create PDFs when scanning

Well then here :smile:

Please do a full restart after the rebuild and before the testing. Can you also give information about the scanners ownership and permissions (lsusb to get its major and minor device node, ls -l /dev/bus/usb/<major>/<minor> to get permission and ownership) and about your users groups (groups)? Last but not least please provide the out of env SANE_DEBUG_DLL=4 scanimage -L.
Also please test scanning to PNG as target file format.

• [x] utsushi backend loaded
• [x] utsushi recognises scanner

To this point, I'm desperate. I'm not sure what could cause this problem. Maybe an upstream regression introduced with the update from 57 to 59.2, but I don't want to point at others :laughing: . Does utsushi output anything on the console?
What about utsushi-scan-cli from utsushis libexec directory?

Thank you for your contributions.
This has been automatically marked as stale because it has had no activity for 180 days.
If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.
Here are suggestions that might help resolve this more quickly:

1. Search for maintainers and people that previously touched the
   related code and @ mention them in a comment.
2. Ask on the NixOS Discourse. 3. Ask on the #nixos channel on
   irc.freenode.net.

I've been having a very similar issue with utsushi and a DS-360W scanner. I've tried to run utsushi-scan-cli, but the result is the same as when running scanimage or utsushi directly: the scan seems to go through, but no output is created.

• scanimage produces the following error:
  scanimage: rounded value of br-x from 214.093 to 214.093 scanimage: received signal 13 scanimage: trying to stop scanner scanimage: sane_read: Operation was canceled
• utsushi-scan-cli fails silently.

[plabadens]

@wucke13 After having done some basic testing on my Arch install, the scanner seems to work fine there, using utsushi (aka imagescan) version 3.63.0. I originally though this might be because of differences between the community build and the Epson upstream version, but the Arch package is using the Epson sources directly (see https://github.com/archlinux/svntogit-community/blob/packages/imagescan/trunk/PKGBUILD). Therefore #76909 might provide a fix for this issue. Do let me know if I can help out with this.

[wucke13]

Sure, if you find the time to prepare an update that would be lovely. I'm still waiting for epson to incorporate a fix for the rotation shell script...

[plabadens]

I've had a look at it, and using the sources from the latest Epson upstream seems to build fine. I'll make a pull request for that later this week if I have the time. However, even v3.63.0 doesn't fix the issue I had. Some other component must be at fault here…

[mwilsoncoding]

I can confirm the same happens with my Epson DS-40. It's quite a frustrating error because it reads the entirety of the scan and then sigterms at EOF.

At the moment, I'm only using scanimage to perform scans and the device is plugged in via usb.

The closest thing I've found to an explanation is this thread- from 2001...

I'll try a non-utsushi scanner in the near future if I can find one.

Relevant parts of my nix config:

# it's a flake
inputs.nixpkgs.url = github:NixOS/nixpkgs/1dc37370c489b610f8b91d7fdd40633163ffbafd; # <- pinned nixpkgs
inputs.darp6.url = github:mwilsoncoding/darp6/dca263e47a5a3d41cef8b5be09c5bafbf63aff52 # <- system76 darter pro 6 base config

outputs = { self, nixpkgs, darp6 }: {
  nixosConfigurations.nixtop = nixpkgs.lib.nixosSystem {
    ...
    hardware.sane.enable = true;
    hardware.sane.extraBackends = [ pkgs.utsushi ];
    services.udev.packages = [ pkgs.utsushi ... ];
    ...
}

[wucke13]

@mwilsoncoding

• AFAIK there is no need to add the driver to udev manually
• Can you reproduce the same behavior when running the GUI, utsushi?
• I think there was a build flag or something to enable verbose output. However, I forgot which one. If you find out, just give add that flag to your package via override and give it a spin, maybe the debug output includes some insightful information?
• Oh, and if this really is a bug in utsushi, try reporting it back to epson itself

[mwilsoncoding]

• Oh, nice! I'll remove the udev mention from my config once all is said and done.

• Using utsushi, I see no error, but also no output <- silent failure.

• Below is the debug output from a test run:

SANE_DEBUG_DLL=4 scanimage -T

• ~Yeah, I should do that thing... might have to make a run somewhere to get my scan onto digital media in the meantime... lol~ ~<- Just did that thing. See comment below.~ Woops, <- that's the community version methinks

[mwilsoncoding]

~First time I've opened an issue with Epson- or on GitLab for that matter.~

~LMK if you think anything should be added for additional context: gitlab/utsushi/utsushi/98~ <- I now understand this is likely the community repo. Looking into how to report this to Epson other than calling customer service.

---

As a note, I wasn't previously a member of the scanner group on my local system. I've added the line and am now in the group, but that doesn't fix the error.

[mwilsoncoding]

Welp- I looked into contacting Epson proper, but according to the product support page:

Important: Epson does not provide support for Linux drivers.

[wucke13]

IIRC Olaf Meeuwissen, the maintainer of the utsushi community repo, stated that he successfully got in touch with epson for a couple of issues in utsushi

[paddy-hack]

Where successfully means a patch got applied without any kind of feedback. Not even so much as a thank you in the mail, let alone a NEWS file or ChangeLog :unamused: I only found out by looking at the diff between their version and getting a feeling of deja vu.

As for contacting EPSON proper, there's an email address in configure.ac. It's what I use.
:warning: It's a worm hole. If anything you send manages to get out to begin with, it (al)most certainly won't end up in your mailbox :angry:

[wucke13]

@paddy-hack Good to hear from you, bad to hear it :laughing: . Any chances that https://gitlab.com/utsushi/utsushi/-/issues/97 is a viable way for you?

[mwilsoncoding]

There's some additional context in gitlab/utsushi/utsushi#98, but I felt it useful to mention here for any other NixOS people stumbling on this repo.

I'm trying to recompile with debug output according to https://gitlab.com/utsushi/utsushi/-/issues/10.

Here's my patch.

And I apply it like so:

hardware.sane.extraBackends = with pkgs: [
  (utsushi.overrideAttrs (oldAttrs: rec {
    patches = [
      (fetchpatch {
        url = "https://gist.githubusercontent.com/mwilsoncoding/ffdd83503ed3e34d5e7d6ee43e8f090b/raw/6c8e3765fc488fcaeb83e13214da9a5f4e8f46df/log.cpp.debug-patch";
        sha256 = "1mzss9f0a98zvzal3pxrcix3g7h4kyr34p7lblqk0359hsprrq7s";
      })
    ];
  }))
];

It's failing at the moment, but, to save myself more duplicate keystrokes, you can check the output in the gitlab issue above.

Also, ~not sure if hugely important or not~ (it is), but nixpkgs is currently set up to utilize the gitlab/utsushi/imagescan source btw, not gitlab/utsushi/utsushi <- for anyone curious about where the code actually comes from.

[paddy-hack]

@paddy-hack Good to hear from you, bad to hear it :laughing: . Any chances that https://gitlab.com/utsushi/utsushi/-/issues/97 is a viable way for you?

I'll be following up on that issue over at GitLab.com but my inbox is bursting at the seems :unamused:

[mwilsoncoding]

@thedavidmeister check out https://github.com/NixOS/nixpkgs/pull/76909

I think that PR should close this issue out.

[thedavidmeister]

@paddy-hack lesson learned, i won't purchase buggy and ungrateful epson in the future, thanks for the effort :bow:
