Comment 86 for bug 1731459

Certainly, the PPA from `rolfbensch` has the fix (start at https://gitlab.com/sane-project/backends/issues/7#note_125319290).

https://gitlab.com/sane-project/backends/-/tags/1.0.28, was released on Jul 31 2019.

At least currently:
https://mirrors.edge.kernel.org/ubuntu/pool/main/s/sane-backends/
libsane-common_1.0.27-1~experimental3ubuntu2.2_..> 30-Aug-2019 15:48 267K <<<< THIS ONE
libsane-common_1.0.27-3.2ubuntu1.1_all.deb 30-Aug-2019 15:48 265K
libsane-common_1.0.27-3.2ubuntu1_all.deb 05-Apr-2019 23:06 265K
libsane-common_1.0.27-3.2ubuntu3_all.deb 19-Sep-2019 12:48 265K

My system was preset for that PPA (due to above).

```
$ dpkg --list | grep -i libsane-common
ii libsane-common 1.0.28+git20191006-bionic0 all API library for scanners -- documentation and support files

/etc/apt/sources.list.d$ grep -rins sane *
rolfbensch-ubuntu-sane-git-bionic.list:1:deb http://ppa.launchpad.net/rolfbensch/sane-git/ubuntu bionic main
rolfbensch-ubuntu-sane-git-bionic.list:2:# deb-src http://ppa.launchpad.net/rolfbensch/sane-git/ubuntu bionic main
```

Remove that PPA and update/refresh (remove libsane*) then re-install
(there is a lot of awkward pkg removals when I tried to remove libsane*, be sure to re-install stuff that you didn't want to remove)

```
$ dpkg --list | grep -i libsane-common
ii libsane-common 1.0.27-1~experimental3ubuntu2.2 all API library for scanners -- documentation and support files

$ dpkg --list | grep -i sane-utils
ii sane-utils 1.0.27-1~experimental3ubuntu2.2 amd64 API library for scanners -- utilities
```

Retested, and == VERIFIED FIXED
