Dear Alexander and Theirry, Last April you helped me install a canon scanner on my Ubuntu 18.04 distribution. I just wanted to Thank you for your help. I was able to install it again on the another computer. This time I never installed any sane backends, just airscan from the github website. I followed the instructions there and it worked. Under /etc/sane.d/ has all the .conf files and this time I see no conf file for ecsl.
Thank you for your help, Anton
