MarsSeed [1] filed a deletion request for cms-germany-git [2]: Unmaintained on AUR, and this server application is broken on Arch Linux, due to upstream only targeting the 4-year-old Ubuntu 20.04 LTS. Users/developers/sysadmins should better build this using upstream's Dockerfile if they want to run it on Arch. Otherwise it is incompatible with Python libraries shipped on Arch, due to upstream's upper version constraints [a], and in many cases, API incompatibility with modules like: - python-babel (required: 2.6, Arch version: 2.15.0) - python-bcrypt (required: 3.1, Arch version: 4.2.1) - python-chardet (required: 3.0, Arch version: 5.2.0) - python-gevent (required: 20.12.0, Arch version: 24.2.1) - python-greenlet (required: 1.0.0, Arch version: 3.1.0) - python-jinja (required: 2.10, Arch version: 3.1.4) - python-markupsafe (required: 2.0.1, Arch version: 2.1.5) - python-netifaces (required: 0.10, Arch version: 2.11.0) - python-patool (not defined in PKGBUILD, required: 1.12, AUR/python- patool version: 3.1.0) - python-psutil (required: 5.5, Arch version: 6.1.0) - python-psycopg2 (required: 2.8, Arch version: 2.9.9) - python-pycryptodomex (required: 3.6, Arch version: 3.21.0) - python-pyxdg (required: 0.26, Arch version: 0.28) - python-pyyaml (required: 5.3, Arch version: 6.0.2) - python-requests (required: 2.22, Arch version: 2.32.3) - python-tornado (required: 4.5, Arch version: 6.4.1) - python-werkzeug (required: 0.16, Arch version: 3.0.4) Also upstream only officially supports Python 3.8.
