Reason: Systemd configuration needed. (Discuss in Talk:Transmission#)

Transmission is a light-weighted and cross-platform BitTorrent client. It is the default BitTorrent client in many Linux distributions.


There are several options in Official Repositories:

includes CLI tools, daemon and web client.


For transmission-gtk and transmission-qt, the default path of configuration files is ~/.config/transmission.

For transmission-cli, default configuration path is ~/.config/transmission-daemon.

Run as a daemon

  • If you cannot find the ~/.config/transmission-daemon folder, run transmission-daemon once to create it.
  • You need to stop the daemon before editing configuration files, or your edits will not be saved.

To run transmission as a daemon, you need have transmission-cli installed. By default, the daemon will run as the user transmission, whose home directory is /var/lib/transmission/.

If you use initscripts, you can change the user in /etc/conf.d/transmissiond:

TRANS_USER="<your user name>"

If you use systemd, you have to override the user in both the service file (/usr/lib/systemd/system/transmission.service) and the tmpfile (/usr/lib/tmpfiles.d/transmission.conf). To do so, copy both files to the appropriate directory in /etc:

# cp /usr/lib/systemd/system/transmission.service /etc/systemd/system/
# cp /usr/lib/tmpfiles.d/transmission.conf /etc/tmpfiles.d/

Create a new group named for example, transmission:

# groupadd transmission

Add your custom user to the newly created [group] ie. transmission:

# gpasswd -a [user] [group]

Then change User= to your custom user in the service file and edit the tmpfile to the following:

d /run/transmission - [user] [group] -

Then run systemd-tmpfiles --create transmission.conf and restart the transmission service.

You may need to reload service files after editing:

# systemctl daemon-reload

Don't forget to change permissions to 777 on folder '/run/transmission'.

Navigate to in web browser and you can see the Web client.

You can also edit the main configuration file ~/.config/transmission-daemon/settings.json or /var/lib/transmission/.config/transmission-daemon/settings.json to fit your preference. Or place a symlink to your media drive in Downloads dir set in config, just make sure the transmission user has rw privileges to your media drive dirs:

ln -s /media/USB_Movies/Downloads /home/user/Downloads
chown user /media/USB_Movies/Downloads

If you would use Transmission daemon with its own group, you have to give the writing permission to transmission group in your download's directory. For this you need to run:

# chgrp transmission /path/to/download
# chmod g+w /path/to/download
