Comment 35 for bug 1707352

Hopefully this bug will be fixed eventually, but for now I found an ugly workaround which made my Brother scanner (brscan3 driver) work again.

- Installed the equivs package.

- Purged libsane1 by 'sudo dpkg --purge --ignore-depends=libsane1 libsane1'.

- Installed the zesty versions of libsane, libsane-common and sane-utils by 'sudo dpkg -i' and marked them not to be upgraded by 'sudo apt-mark hold libsane libsane-common sane-utils'.

- Created a controlfile 'libsane1' by 'equivs-control libsane1' and edited it so that it looks like this:

Description: dummy package
 dummy package for libsane1

------------

- Built a dummy package libsane1_99_all.deb by 'equivs-build libsane1' and installed it by 'sudo dpkg -i' to satisfy dependencies.
