Did the verification using a Brother MFC-240C USB scanner. Preparations:
* Installed brscan2 (brscan2-0.2.5-1.amd64.deb) * Installed libusb-0.1-4 (ought to be a dependency of brscan2 but that's not the case) * Added myself to the lp group (sudo adduser $USER lp) focal ----- Verified the test case using version 1.0.29-0ubuntu5.2 of libsane, libsane-common and sane-utils from focal-proposed. The scanner was found and I could scan. bionic ------ Verified the test case using version 1.0.27-1~experimental3ubuntu2.4 of libsane1, libsane-common and sane-utils from bionic-proposed. The scanner was found, which is an improvement, but I could not scan. brscan2 installs files not only in /usr/lib64/sane, but also directly in /usr/lib64, and to be able to scan I had to add one of the symlinks previously used to work around the absence of the proposed fix: $ ls -l /usr/lib/libbr* lrwxrwxrwx 1 root root 31 sep 19 02:49 /usr/lib/libbrscandec2.so -> ../lib64/libbrscandec2.so.1.0.0 So in my case this proved to be a fragile solution for bionic. But for drivers which only installs in /usr/lib64/sane it should be a safe solution of a long standing issue. Conclusion ---------- Even if the solution isn't sufficient for bionic in my case, it's a step in the right direction, and I would consider the proposed upload verified for both focal and bionic. ** Tags removed: verification-needed verification-needed-bionic verification-needed-focal ** Tags added: verification-done verification-done-bionic verification-done-focal -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1835220 Title: Please support /usr/lib64/sane Status in sane-backends package in Ubuntu: Fix Committed Status in sane-backends source package in Bionic: Fix Committed Status in sane-backends source package in Focal: Fix Committed Status in sane-backends source package in Groovy: Fix Committed Status in sane-backends package in Baltix: Confirmed Status in sane-backends package in Debian: New Bug description: [Impact] The patch 0125-multiarch_dll_search_path.patch makes /usr/lib/sane be recognized as a directory for SANE backends. However, some .deb files with scanner drivers, typically provided by Brother, install files in /usr/lib64/sane. This issue has been discussed in bug #1728012, but was broken out from there to not block another more important change in bionic. sane-backends 1.0.31-1~experimental1 adds support for /usr/lib64/sane, and so do the debdiffs attached to this bug report for focal and bionic. [Test case] * Configure an affected scanner with drivers installed via e.g. brscan2 * Try to scan with simple-scan -> Find that the scanner is not found * Install libsane{,1}, libsane-common and sane-utils from {focal,bionic}-proposed * Try to scan again -> Scanner found and scanning works [Regression risk] This only adds a directory to the lib search path via an existing patch, so the regression risk should be minimal.
