I am using Ubuntu 16.04 and my scanner, Brother MFC-495CW, is working fine. However I wanted to test Ubuntu 18.04 and installed it on a separate hard-drive. I followed the same instructions as for 16.04 but cannot make the scanner work on 18.04. When using "Simple Scan" I get Failed to scan, no scanners available. Please connect a scanner. Please help.

add these two symbolic links
sudo ln -sfr /usr/lib64/libbrscandec* /usr/lib/x86_64-linux-gnu sudo ln -sfr /usr/lib64/sane/libsane-brother* /usr/lib/x86_64-linux-gnu/sane
(ie you need to copy each command above; line by line; paste into a terminal; hit the ENTER key and move to second line ..) re-boot ....... any joy?
