Fixing Transmission Daemon’s “Permission Denied” Error on Xubuntu

Ubuntu 5

When using Transmission Daemon on Xubuntu for torrenting, you may encounter the “Permission Denied” error. This error typically arises due to incorrect permissions or ownership of the download directory. This article will guide you through the process of identifying and rectifying this issue.

Quick Answer

To fix the "Permission Denied" error in Transmission Daemon on Xubuntu, you need to identify the user running the daemon, check the ownership and permissions of the download directory, change the ownership and permissions if necessary, modify the Transmission configuration file, and restart the daemon. By following these steps, you should be able to resolve the error and continue using Transmission on Xubuntu.

Identifying the User Running Transmission Daemon

The first step in resolving the “Permission Denied” error is to identify the user running the Transmission daemon. You can do this by executing the following command in the terminal:

ps -ef | grep transmission

or

ps aux | grep transmission

These commands list the processes associated with Transmission. The user running the daemon is typically listed in the first column of the output.

Checking the Ownership and Permissions of the Download Directory

Next, check the ownership and permissions of the download directory. You can use the ls -l command for this:

ls -l /path/to/your/download/directory

Replace /path/to/your/download/directory with the actual path to your download directory. This command lists the files and directories along with their ownership and permissions. The owner and group are displayed in the third and fourth columns respectively.

Changing the Ownership and Permissions

If the ownership and permissions are incorrect, you can change them using the chown and chmod commands. The chown command changes the owner and group of a file or directory:

sudo chown -R debian-transmission:debian-transmission /path/to/your/download/directory

The -R option makes the command recursive, meaning it applies to the directory and its contents. Replace debian-transmission:debian-transmission with the user and group running the Transmission daemon, and /path/to/your/download/directory with the path to your download directory.

The chmod command changes the permissions of a file or directory:

sudo chmod -R 770 /path/to/your/download/directory

The -R option makes the command recursive. The 770 permissions give the owner and group read, write, and execute permissions, and no permissions to others.

Modifying the Transmission Configuration File

After adjusting the permissions, you need to modify the Transmission configuration file. First, stop the Transmission daemon:

sudo service transmission-daemon stop

Next, open the configuration file for editing:

sudo nano /etc/transmission-daemon/settings.json

In the configuration file, locate the line "umask": 18 and change it to "umask": 2. The umask setting controls the permissions of files created by Transmission. A umask of 2 results in files with 664 permissions (read and write for the owner and group, and read for others), which should allow Transmission to write to the download directory.

After making the change, save the file by pressing Ctrl+O and then exit the editor by pressing Ctrl+X.

Finally, start the Transmission daemon again:

sudo service transmission-daemon start

By following these steps, you should be able to resolve the “Permission Denied” error in Transmission Daemon on Xubuntu. If you continue to experience issues, consult the Transmission Daemon documentation or seek help from the Xubuntu community.
