Package: mailman3-web Version: 0+20180916-2~bpo9+1 Severity: grave Dear Maintainer,
mailman3-web-qcluster.service ExecStart is missing absolute path to python3: # systemctl cat mailman3-web-qcluster.service |egrep '^#|Exec' # /lib/systemd/system/mailman3-web-qcluster.service ExecStart=python3 /usr/bin/django-admin qcluster --pythonpath /usr/share/mailman3-web --settings settings This causes systemd (232-25+deb9u6) to fail with the following: [/lib/systemd/system/mailman3-web-qcluster.service:8] Executable path is not absolute, ignoring: python3 /usr/bin/django-admin qcluster --pythonpath /usr/share/mailman3-web --settings settings mailman3-web-qcluster.service: Service lacks both ExecStart= and ExecStop= setting. Refusing. Has this requirement been relaxed in systemd in stretch-backports? Is this a missing dependency? Regardless, just changing python3 to /usr/bin/python3 is enough: ExecStart=/usr/bin/python3 /usr/bin/django-admin qcluster --pythonpath /usr/share/mailman3-web --settings settings Then restarting the service works: # systemctl daemon-reload # systemctl restart mailman3-web-qcluster.service -- System Information: Debian Release: 9.6 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-8-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages mailman3-web depends on: ii dbconfig-pgsql 2.0.8 ii dbconfig-sqlite3 2.0.8 ii debconf [debconf-2.0] 1.5.61 ii lsb-base 9.20161125 ii node-less 1.6.3~dfsg-2 ii python3 3.5.3-1 ii python3-django-hyperkitty 1.2.1-4~bpo9+1 ii python3-django-postorius 1.2.2-4~bpo9+2 ii python3-psycopg2 2.6.2-1 ii python3-whoosh 2.7.0-2 ii ruby-sass 3.4.23-1 ii ucf 3.0036 ii uwsgi 2.0.14+20161117-3+deb9u2 ii uwsgi-plugin-python3 2.0.14+20161117-3+deb9u2 Versions of packages mailman3-web recommends: ii libapache2-mod-proxy-uwsgi 2.0.14+20161117-3+deb9u2 Versions of packages mailman3-web suggests: ii default-mysql-server 1.0.2 ii mariadb-server-10.1 [virtual-mysql-server] 10.1.37-0+deb9u1 ii postgresql 9.6+181+deb9u2 -- Sampo Sorsa Sent with ProtonMail Secure Email.
