For Raspbian_9.0 in root :
$ curl -fsSL 
https://download.opensuse.org/repositories/home:/thierry1970/Raspbian_9.0/Release.key 
| gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/Ubuntu_debbuild.gpg > 
/dev/null

For Raspbian_10 in root :
$ curl -fsSL 
https://download.opensuse.org/repositories/home:/thierry1970/Raspbian_10/Release.key 
| gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/Ubuntu_debbuild.gpg > 
/dev/null

After

$ sudo apt update
$ sudo apt install libsane libsane-commmon sane-utils
