The daemon itself runs fine in the foreground, and manual execution shows no issues. It appears that the systemd service script is waiting for a readiness message that is no longer sent by the current version of Transmission. Steps to Reproduce: Install Xubuntu/Ubuntu on a fresh system. Install transmission-daemon using sudo apt install transmission-daemon. Modify the configuration in /etc/transmission-daemon/settings.json as needed. Start the service with sudo systemctl start transmission-daemon. Observe that the service fails with a timeout error. Expected Behavior: Transmission-daemon should start without timing out when launched via systemd. Actual Behavior: Transmission-daemon starts fine in the foreground but fails to report its status correctly to systemd, resulting in a timeout error. Workaround: Changing the systemd service file by adjusting the ExecStart command to explicitly specify the configuration directory (e.g., adding --config-dir /etc/transmission-daemon) and possibly setting Type=simple along with an increased TimeoutStartSec resolves the issue. - Description: Ubuntu 24.04.2 LTS Release: 24.04 transmission-daemon: - Installed: 4.0.5-1build5 - Candidate: 4.0.5-1build5 - Version table: - *** 4.0.5-1build5 500 - 500 http://us.archive.ubuntu.com/ubuntu noble/universe amd64 Packages - 100 /var/lib/dpkg/status + Installed: 4.0.5-1build5 + Candidate: 4.0.5-1build5 + Version table: + *** 4.0.5-1build5 500 + 500 http://us.archive.ubuntu.com/ubuntu noble/universe amd64 Packages + 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: transmission-daemon 4.0.5-1build5 [modified: lib/systemd/system/transmission-daemon.service] ProcVersionSignature: Ubuntu 6.8.0-56.58-generic 6.8.12 Uname: Linux 6.8.0-56-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.28.1-0ubuntu3.5 Architecture: amd64 CasperMD5CheckResult: unknown Date: Tue Mar 25 20:39:26 2025 InstallationDate: Installed on 2025-03-26 (0 days ago) InstallationMedia: Xubuntu 24.04.1 LTS "Noble Numbat" - Release amd64 (20240827) ProcEnviron: - LANG=en_US.UTF-8 - PATH=(custom, no user) - SHELL=/bin/bash - TERM=xterm-256color - XDG_RUNTIME_DIR=<set> + LANG=en_US.UTF-8 + PATH=(custom, no user) + SHELL=/bin/bash + TERM=xterm-256color + XDG_RUNTIME_DIR=<set> SourcePackage: transmission UpgradeStatus: No upgrade log present (probably fresh install) modified.conffile..etc.transmission-daemon.README.json: [deleted] modified.conffile..etc.transmission-daemon.settings.json: [deleted]
