lide100 scanners produce a white/orange band in scanned images on Ubuntu 18.04

[Chris]

Maybe this bug is the same shown in https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1731459 ...

I've 2 Canon Lide 100 scanners. Both works well with ubuntu 16.04.
Running them on ubuntu 18.04 it first shows a black bar across the scanned page,
after some updates (apt-get update) it currently shows white and orange bars.

Booting my system with the old installed 16.04 both scanners works well,
running 18.04 both scanners show the black/white/orange-bar effect.

Reading at bug-report 1731459 that this is fixed in 1.0.27 original, I downloaded
the daily-tar-gz from http://www.sane-project.org/snapshots/sane-backends-git20180806.tar.gz,
compile and replace the /usr/lib/x86_64-linux-gnu/sane/libsane-genesys.so.1.0.27.

Unfortunately it does not work as describe. Removing this lib, simple-scan could not find
the scanner, so i think a replaced the right one.

This bug is now nearly 9 month old and reported, please Canonical could you fix this !

Followed the instructions from "Gabriel N. <email address hidden>", posted Fri, 05th Oct 2018,
works fine for me, just changed the ./configure-option from defaults to "--prefix=/usr --sysconfdir=/etc --localstatedir=/var".

After install the patched libsane1_1.0.27-1~experimental3ubuntu2_amd64.deb, do a "ldconfig" and start the simple-scan prog, booting the OS was not necessary.

Both of my Lide 100 now works as expected.

Hope the ubuntu-guys would insert this simple patch in the near time also ...

greetings to all
