Package: devscripts Version: 2.26.11 Severity: normal Tags: patch Dear Maintainer,
The refactor of the mmdebstrap builder that closed #1140552 introduced another issue. It now makes all debrebuild --builder=mmdebstrap commands fail if anything is set in the Environment section. > "--chrooted-customize-hook=env --chdir=$quoted_custom_build_path " > . (map String::ShellQuote::shell_quote, @environment) > . " dpkg-buildpackage -uc -a $host_arch --build=$build", The trailing string concatenation forces `map` into scalar context, in which it returns the count of elements. For a buildinfo with N Environment lines the customize-hook becomes `env --chdir=<path> N dpkg-buildpackage ...`, and env fails with `env: 'N': No such file or directory`. It's reproducible by running the following: $ curl -sfLO https://buildinfos.debian.net/buildinfo-pool/h/hello/hello_2.12.3-1_amd64.buildinfo $ debrebuild --builder=mmdebstrap --buildresult=./out hello_2.12.3-1_amd64.buildinfo [...] I: running --chrooted-customize-hook in shell: sh -c 'env --chdir=/build/reproducible-path/hello-2.12.3 5 dpkg-buildpackage -uc -a amd64 --build=any' env: '5': No such file or directory E: command failed: env --chdir=/build/reproducible-path/hello-2.12.3 5 dpkg-buildpackage -uc -a amd64 --build=any I've attached a patch that resolves the problem for me.
