Syncthing service won't start automatically

Support
1

Hello, good morning.

After each system reboot (I’m using Ubuntu 25.04), the Syncthing service doesn’t start automatically. I always have to start it manually with systemctl enable --now syncthing@myusername.service. How should I proceed?

Thanks.

Are you using an encrypted home directory?

No.

What status does systemd report for the unit before you issue that command? There are some subcommands in systemctl to check dependencies. You should check those in addition.

Where did you get the systemd service file from? How did you install Syncthing at all?
