Uh, option (b) is a bigger can of worms. One of rpds-py build-depends is python3-maturin, which is not available on i386.
Checking python-maturin's BDs shows dozens of rust packages, none of which are available in i386: The following packages have unmet dependencies: sbuild-build-depends-main-dummy : Depends: librust-anyhow-dev (>= 1.0.63) but it is not installable Depends: librust-base64-dev (>= 0.13.0) but it is not installable Depends: librust-bytesize-dev but it is not installable Depends: librust-cargo-config2-dev but it is not installable Depends: librust-cargo-metadata-dev (>= 0.14.2) but it is not installable Depends: librust-cargo-options-dev but it is not installable Depends: librust-cbindgen-dev but it is not installable Depends: librust-cc-dev (>= 1.0.72) but it is not installable Depends: librust-clap-dev (>= 4.0.0) but it is not installable Depends: librust-configparser-dev but it is not installable Depends: librust-console-dev (>= 0.15) but it is not installable Depends: librust-dialoguer-dev but it is not installable Depends: librust-dirs-dev (>= 4.0.0) but it is not installable Depends: librust-dunce-dev (>= 1.0.2) but it is not installable Depends: librust-expect-test-dev but it is not installable Depends: librust-fat-macho-dev but it is not installable Depends: librust-flate2-dev (>= 1.0.18) but it is not installable Depends: librust-fs-err-dev but it is not installable Depends: librust-glob-dev but it is not installable Depends: librust-goblin-dev (>= 0.6) but it is not installable Depends: librust-ignore-dev (>= 0.4.18) but it is not installable Depends: librust-indexmap-dev (>= 2) but it is not installable Depends: librust-indoc-dev but it is not installable Depends: librust-itertools-dev (>= 0.10) but it is not installable Depends: librust-lddtree-dev but it is not installable Depends: librust-minijinja-dev but it is not installable Depends: librust-normpath-dev but it is not installable Depends: librust-once-cell-dev (>= 1.7.2) but it is not installable Depends: librust-path-slash-dev but it is not installable Depends: librust-pep440-rs-dev but it is not installable Depends: librust-pep508-rs-dev but it is not installable Depends: librust-platform-info-dev (>= 1.0.0) but it is not installable Depends: librust-pretty-assertions-dev but it is not installable Depends: librust-pyproject-toml-dev but it is not installable Depends: librust-python-pkginfo-dev (>= 0.6.3) but it is not installable Depends: librust-regex-dev (>= 1.7.0) but it is not installable Depends: librust-rpassword-dev (>= 6.0.0) but it is not installable Depends: librust-rstest-dev but it is not installable Depends: librust-rustc-version-dev (>= 0.4.0) but it is not installable Depends: librust-rustls-dev but it is not going to be installed Depends: librust-rustversion-dev but it is not installable Depends: librust-semver-dev (>= 1.0.13) but it is not installable Depends: librust-serde-dev (>= 1.0.141) but it is not installable Depends: librust-serde-json-dev (>= 1.0.80) but it is not installable Depends: librust-sha2-dev (>= 0.10.3) but it is not installable Depends: librust-tar-dev (>= 0.4.38) but it is not installable Depends: librust-target-lexicon-dev (>= 0.12.0) but it is not installable Depends: librust-tempfile-dev (>= 3.2.0) but it is not installable Depends: librust-textwrap-dev (>= 0.16.0) but it is not installable Depends: librust-thiserror-dev (>= 1.0.37) but it is not installable Depends: librust-time-dev (>= 0.3) but it is not installable Depends: librust-toml-edit-dev but it is not installable Depends: librust-tracing-dev but it is not installable Depends: librust-tracing-subscriber-dev but it is not installable Depends: librust-trycmd-dev but it is not installable Depends: librust-which-dev but it is not installable Depends: librust-zip-dev (>= 0.6.1) but it is not installable Depends: python3-tomli but it is not installable -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2104170 Title: FTBFS on i386: unresolvable deps To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/jq/+bug/2104170/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
