[Desktop-packages] [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
Slightly updated patch instructions from above.
--- CUT HERE ---
sudo apt-get install dpkg-dev fakeroot
# in Synaptic, Ubuntu Settings >> Repositories, enable "Source code"
apt-get source libsane1
# eyeball first for any error messages
patch sane-backends-1.0.27/backend/genesys.c --dry-run < genesys.c.diff
# if the above was successful
patch sane-backends-1.0.27/backend/genesys.c < genesys.c.diff
sudo apt-get build-dep libsane1
cd sane-backends-1.0.27
./configure
dpkg-buildpackage -rfakeroot -uc -b
cd ..
sudo rm /usr/share/doc/libsane1/changelog.Debian.gz
sudo dpkg -i libsane1_1.0.27-1~experimental3ubuntu2_amd64.deb
# reboot
--- CUT HERE ---
Also:
- If any of the steps above fails, examine the entire output carefully
line by line for error information about any possible missing packages,
e.g. "Check if the 'dpkg-dev' package is installed". Simply use "sudo
apt-get install " to install anything that is missing.
- Unless you lock the libsane1 package in apt ("sudo apt-mark hold
") and in Synaptic (Synaptic >> Package >> Lock Version), your
next automated or manual Ubuntu update might re-install the original,
unpatched libsane1 package. Those two package maintenance systems use
independent locking mechanisms that are not synchronized.

FYI, @ramas (slocascio), fermulator (fermulator) and Alec B (castegere) instructions - slightly updated and automated for Ubuntu 18.04.1 (libsane1_1.0.27-1~experimental3). Also, I expanded the patch to test for both "slow_back_home" and "rewind", just in case it matters for some hardware. --- cut here --- # in Synaptic, Ubuntu Settings >> Repositories, enable "Source code" apt-get source libsane1 # eyeball first patch sane-backends-1.0.27/backend/genesys.c --dry-run < genesys.c.diff # if the above was successful patch sane-backends-1.0.27/backend/genesys.c < genesys.c.diff sudo apt-get build-dep libsane1 cd sane-backends-1.0.27 ./configure sudo apt-get install fakeroot dpkg-buildpackage -rfakeroot -uc -b cd .. sudo rm /usr/share/doc/libsane1/changelog.Debian.gz sudo dpkg -i libsane1_1.0.27-1~experimental3ubuntu2_amd64.deb # reboot --- cut here --- ** Patch added: "genesys.c.diff" https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1731459/+attachment/5197760/+files/genesys.c.diff -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1731459 Title: genesys_gl847 scanners produce a black band in scanned images on Ubuntu 17.10+ (and 18.04 LTS) Status in sane-backends package in Ubuntu: Confirmed Bug description: On Windows it works but on my Ubuntu 17.10 I see a black band on scanned image.
