This bug is serious for me as I use my scanner everyday. I am under Lubuntu 17.10.
For who like me cannot wait the official patch, can follow how I did solve: 1. get the source not from git but from the official package manager with command: apt-get source libsane1 it did download and create the directory sane-backends-1.0.27/ 2. modify the lines 2075-2077 of file sane-backends-1.0.27/backend/genesys.c into: if (dev->model->flags & GENESYS_FLAG_SHADING_REPARK && dev->model->cmd_set->slow_back_home) { status = dev->model->cmd_set->slow_back_home (dev, dev->model->flags ); 3. build the dependencies with command: sudo apt-get build-dep libsane1 4. I had to copy the file /usr/share/aclocal/libtool.m4 into sane- backends-1.0.27/m4 as the build process complained it was missing 5. then build the fixed package with command: cd sane-backends-1.0.27 dpkg-buildpackage -rfakeroot -uc -b 6. then install the updated package with command: cd .. sudo dpkg -i libsane1_1.0.27-1~experimental2ubuntu2.1_amd64.deb 7. I did restart my PC (but I do not know if this is necessary) 8. My simple-scan gui program did output a clean scan!! reference here: https://askubuntu.com/questions/28372/how-do-i-get-and- modify-the-source-code-of-packages-installed-through-apt-get/28373#28373 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1731459 Title: genesys_gl847 scanners produce a black band in scanned images on Ubuntu 17.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1731459/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
