Package: librtlsdr0 Version: 0.6.0-5 Severity: important Tags: patch User: helm...@debian.org Usertags: dep17p7 X-Debbugs-Cc: helm...@debian.org
librtlsdr0 contains udev rules which are installed to /lib; the rules file needs to be moved to /usr/lib as part of Debian's usr-merge effort. Because librtlsdr0 is Multi-Arch: same, an unfortunate corner- case can occur whereby shared files (such as udev rules) may be erroneously removed on upgrades (please see DEP17[1] P7: Shared multiarch file loss). I have raised a Salsa MR[2] and attached an equivalent patch which avoids the problem by implementing DEP17 M10 (Protective diversions for shared files) for the affected file. Please consider applying this patch at your earliest convenience. This bug will be upgraded to release critical soon, as it blocks the overall usr-merge effort which is being undertaken for the trixie release.
