Many scanners can no more be used since sane has changed something: The 3rd-party plug-in the vendor provides as .deb package will still install. But the scanner is no more recognized.

[Impact]
* Starting with Ubuntu 17.10, Ubuntu changed the directory where sane dll looks for third party drivers. This configuration effectively broke backward compatibility for all existing third-party drivers.
* A large swath of these third party drivers (most of them) are no longer supported by the OEM, so maintaining compatibility is important.
* No open source replacement drivers are currently available, nor does the community have the resources to easily replace them.
* This bug represents a substantial portion of the scanners in use.

* This was working in the 17.04 release. 18.10 is an LTS release, so backporting is warranted for the 18.10 release.
[Test Case]
* Following the standard installation procedures for any of the affected scanner drivers results in the driver files being installed to /usr/lib/sane/, and sane looking for them in /usr/lib/x86_64-linux-gnu/sane. When xsane is run, the scanner is not found.
[Regression Potential]
* Regression to previous working sane package often results in the automatic removal of core system components (documented in the comments to this bug report), making regression an unusable option for addressing this bug.
* The available patch is functional and stable in the 19.10 branch.
[Other Info]
* Third party sane drivers in previous version of sane were located under /usr/lib/sane/, however, the current version of sane on Ubuntu only looks for 64 bit drivers under the /usr/lib/x86_64-linux-gnu/sane directory. /usr/lib64 and /usr/lib64/sane are other directories old drivers are known to install files to.
* The addition of symlinks alone does not appear to fix this issue, though it may make the scanner detectable. Changes to udev rules are also needed to allow proper communications to the scanners. A selection of workarounds, including working (though not ideal) udev rules for a number of scanners has been posted to the sane troubleshooting guide: help.ubuntu.com/community/sane_Troubleshooting#The_symlink_and_udev_tricks |

* This was working in the 17.04 release. 18.04 is an LTS release, so backporting is warranted for the 18.04 release.
[Test Case]
* Following the standard installation procedures for any of the affected scanner drivers results in the driver files being installed to /usr/lib/sane/, and sane looking for them in /usr/lib/x86_64-linux-gnu/sane. When xsane is run, the scanner is not found.
* Install the libsane1, libsane-common and sane-utils packages from bionic-proposed and confirm that it now finds drivers in /usr/lib/sane.
[Regression Potential]
* The proposed change is based on an upstream commit, and the patch is functional and stable in both 19.04 and 19.10. Low regression risk.
[Other Info]
* Third party sane drivers in previous version of sane were located under /usr/lib/sane/, however, the current version of sane on Ubuntu only looks for 64 bit drivers under the /usr/lib/x86_64-linux-gnu/sane directory. /usr/lib64 and /usr/lib64/sane are other directories old drivers are known to install files to.
* The addition of symlinks alone does not appear to fix this issue, though it may make the scanner detectable. Changes to udev rules are also needed to allow proper communications to the scanners. A selection of workarounds, including working (though not ideal) udev rules for a number of scanners has been posted to the sane troubleshooting guide: help.ubuntu.com/community/sane_Troubleshooting#The_symlink_and_udev_tricks |

[Impact]
* Starting with Ubuntu 17.10, Ubuntu changed the directory where sane dll looks for third party drivers. This configuration effectively broke backward compatibility for all existing third-party drivers.
* A large swath of these third party drivers (most of them) are no longer supported by the OEM, so maintaining compatibility is important.
* No open source replacement drivers are currently available, nor does the community have the resources to easily replace them.
* This bug represents a substantial portion of the scanners in use.
