Source: grass Version: 7.8.5-2 Tags: upstream Dear Maintainer,
your package build-depends on autoconf2.13, which is obsolete and orphaned in Debian. Please investigate migrating away from autoconf2.13, possibly to autoconf 2.69 or newer (package name "autoconf"). I see Bas already filed a bug report upstream: https://github.com/OSGeo/grass/issues/560 Best, Chris
