[Bug 1731459] Re: genesys_gl847 scanners produce a black band in scanned images on Ubuntu 17.10+, 18.04 LTS and 18.10 Cosmic cuttlefish

[Gunnar Hjalmarsson]

@Simon: That's because I had been lazy and not uploaded to disco (since
it's identical with the package version in eoan). But I just uploaded to
disco, so now (i.e. in a few minutes) you should be able to do:

sudo apt update

to fix it.

My apologies.

Title:
  genesys_gl847 scanners produce a black band in scanned images on
  Ubuntu 17.10+,  18.04 LTS and 18.10 Cosmic cuttlefish

Status in sane-backends package in Ubuntu:

Bug description:
  [Impact]

  When using a Genesys GL847 scanner, the documents get disfigured by a
  discolored bar. The proposed uploads should fix the issue. They are
  available in this PPA:

  https://launchpad.net/~gunnarhj/+archive/ubuntu/sane-backends

  [Test case]

  1. Install the libsane (libsane1 in bionic), libsane-common
     and sane-utils packages from {bionic,disco]-proposed.

  2. Use an affected device to scan, and find that the issue is
     no longer present.

  [Regression risk]

  Upstream commit, focused bug fix => low regression risk

  [Original description]

  On Windows it works but on my Ubuntu 17.10, 18.04 and 18.10 I see a
  black band on scanned image. The scanner is Canon CanoScan LIDE100.
  Libsane version is 1.0.27-1~experimental2ubuntu1
