[sane-devel] brother-MFC-J485DW fails after update.

[Thierry HUCHARD]

Hi,

the Brother driver is not free.
report the bug to: https://support.brother.comotre scanner is supported 
by the free escl and sanr-airscan driver.
I suggest you update your sane version:
sudo add-apt-repository ppa:rolfbensch/sane-git
sudo apt-get update
sudo apt install libsane libsane-common sane-utils
