Hi, https://release.debian.org/transitions/html/python3.7-default.html says: "Affected: .build-depends ~ /python3-dev/"
But that doesn't suffice, there's likely a "| .build-depends ~ /python3-all-dev/" missing. Affected source package is e.g. libarcus whose binary package python3-arcus is currently uninstallable, but has no python3-dev in the build-dependencies: Build-Depends: debhelper (>= 10.2.1), cmake (>= 2.8.12), dh-python, libprotobuf-dev (>= 3.0.0), libprotoc-dev (>= 3.0.0), protobuf-compiler (>= 3.0.0), python3-all-dev, python3-sip-dev The same counts for python3-savitar and src:libsavitar: Build-Depends: debhelper (>= 10.2.1), cmake (>= 2.8.12), dh-python, libpugixml-dev (>= 1.7), python3-all-dev, python3-sip-dev (>= 4.19.12+dfsg-1) | python3-sip-dev (<< 4.19.11+dfsg-1) P.S.: I'm not subscribed to the bug report, please Cc on reply.
