I spent really long time googling this, but I didn't find the answer. My main account to using this server is called admin. I'm mounting my hdd (formatted in exfat) via fstab.

UUID=5AAC-E163 /home/admin/films exfat defaults,users,uid=admin,gid=admin 0 0

my start of /etc/init.d/transmission-daemon (I changed only the user part)

NAME=transmission-daemon DAEMON=/usr/bin/$NAME USER=admin STOP_TIMEOUT=30

strange is that can't change chown of /home/admin/films even with root.

sudo chown debian-transmission:debian-trasmission /home/admin/films

It writes to me: Operation not permitted

And finally, my question, why on earth every time when i add torrent it writes to me that permission was denied.

  • Please add to your question how you run chown (your complete input) and the error message.

  • chown debian-transmission:debian-trasmission is "debian-trasmission" correct?

  • Can you find some related messages in the journal, e.g. with journalctl -ex? Please give us the output of apt list exfat* and findmnt -t exfat.

1 Answer 1


So i finally found out the solution. It is based on a fact that user permissions do not work in exfat. to be clear, you can't change permissions after you mount, so how you mount, it that will remain to the future.

Solution is add umask=0000 in settings when mounting, in my case in fstab.
