Transmission daemon: permission denied even if debian-transmission has root group

I've got something really strange. Transmission-daemon keeps telling me

"Permission denied /home/transmission/downloads/.." (.. = name of torrent folder and files)

I created this folder transmission:

sudo mkdir /home/transmission

After this I've created folders inside:

sudo mkdir /home/transmission/incomplete
sudo mkdir /home/transmission/downloads

Give permission first just by making these folders from debian-transmission:

sudo chgrp -R debian-transmission:debian-transmission /home/transmission

Added myself to this group:

sudo usermod -a -G debian-transmission kurt

But still no access I could edit and add files to the downloads folder so I've added my group kurt to debian-transmission.

sudo usermod -a -G kurt debian-transmission

Permission denied.. hmmm. Okay then chmod this folder to 777.

sudo chmod 777 -R /home/transmission

Permission denied.. last thing I could do:

sudo usermod -a -G root debian-transmission

But nothing helps. I know this is not a good way. But I just wanted to test if this would work. I've restarted transmission service after every permission change just to be sure. Some extra information:

ps aux | grep transmission
output:
117      17319  0.4  0.4 397624 10196 ?        Ssl  18:33   0:05 /usr/bin/transmission-daemon -f --config-dir /var/lib/transmission-daemon/info
kurt     17767  0.0  0.0  13580   900 pts/0    S+   18:52   0:00 grep --color=auto transmission

ps -ef | grep transmission

kurt     17827 17229  0 18:53 pts/0    00:00:00 grep --color=auto transmission

groups debian-transmission
debian-transmission root kurt

groups kurt
kurt adm cdrom sudo dip plugdev lpadmin sambashare debian-transmission

Anyone that has a good solution for my problem?

Solution 1:

Try this:

mkdir /your_path/progress
mkdir /your_path/completed
sudo usermod -a -G debian-transmission your_user
chgrp debian-transmission /your_path/progress
chgrp debian-transmission /your_path/completed
chmod 770 /your_path/progress
chmod 770 /your_path/completed
sudo service transmission-daemon stop
sudo adduser your_user debian-transmission
sudo nano /etc/init.d/transmission-daemon
sudo chown your_user -R /var/lib/transmission-daemon/info/
sudo chown your_user -R /your_path/progress
sudo chown your_user -R /your_path/completed
sudo chown your_user -R /etc/transmission-daemon/settings.json

And change in the file: sudo nano /etc/transmission-daemon/settings.json

"rpc-whitelist": "127.0.0.1" > "rpc-whitelist": "*.*.*.*",
"rpc-password": "password" > "rpc-password": "your_password",
"download-dir": "/var/lib/transmission-daemon/downloads" > "download-dir": "/your_path/completed"
"incomplete-dir": "/var/lib/transmission-daemon/downloads" > "incomplete-dir": "/your_path/progress"

Just restart the daemon:

service transmission-daemon start

Solution 2:

After hours of trial and error........this is what I did:

1.- edit /etc/init.d/transmission-daemon and set the "USER" variable to "root" to solve the folder permission issues

2.- edit /etc/default/transmission-daemon and set "CONFIG_DIR" variable to "/etc/transmission-daemon/" because I don't like having the config file in /var
