Transmission-daemon - Folder permissions issue

Transmission-daemon can't write to a Downloads folder.

(I have installed and used transmission before, and i dont remember ever having trouble with it, i have read these forums and i cant find an answer.)

Ubuntu 22.04, recently / fresh installation and Transmission-daemon. Any assistance with this will be greatly appreciated ! :) Thanks

To my understanding, this is saying the transmission-daemon is running as the user 'debian-transmission' ;

!
My_User@Store:~$ ps ax o user:20,pid,pcpu,pmem,vsz,rss,stat,start_time,time,cmd | grep trans
!
debian-transmission    52574  0.1  0.3 178152 11332 Ssl  Oct21 00:00:57 /usr/bin/transmission-daemon -f --log-error
!

Folder permissions show debian-transmission has rw permissions;

!
My_User@Store:~/Downloads$ ls -l
total 12
drwxrwx--- 2 debian-transmission debian-transmission 4096 Oct  9 13:08 Torrent_Files
drwxrwx--- 2 debian-transmission debian-transmission 4096 Oct 21 21:11 Torrents_Complete
drwxrwx--- 2 debian-transmission debian-transmission 4096 Oct  9 13:07 Torrents_Downloading
!

I'm not sure how relevant this is, but the init.d user for transmission-daemon is set as debian-transimission;

!
/init.d/transmission-daemon
!
NAME=transmission-daemon
DAEMON=/usr/bin/$NAME
USER=debian-transmission
STOP_TIMEOUT=30
!

syslog error when transmission tries to write to the folder;

Not sure if you ever solved this, but I was just having the same issue (same error code at least) and found that while the specific folder I was trying to download the torrent to (./Torrents/Downloads) was owned by debian-transmission:debian-transmission, the parent folder (./Torrents) was owned by USERNAME:users.

I'm not sure why this was needed, but I found that changing the ownership of the parent folder to debian-transmission:debian-transmission resolved the issue.
