**What type of hardware are you using** : Old laptop or computer
**What YunoHost version are you running** : 12.1.39
**How are you able to access your server** : SSH
**Are you in a special context or did you perform specific tweaking on your YunoHost instance ?** : I made a symbolic link from `/home/yunohost.app/transmission` directory to my ZFS drives `/mnt/hermes/transmission/completed`. I did this months ago.
### Describe your issue
Tried to upgrade Transmission but it failed. Shows lots of messages like this and then eventually fails.
```auto
Warning: setfacl: /home/yunohost.multimedia/share/Torrents: Operation not supported
Warning: setfacl: /home/yunohost.multimedia/share/Torrents/completed: Operation not supported
```

On my side, I have transmission installed, with links too, but not the sames as you…
Here they are :
```auto
/home/yunohost.transmission → /home/yunohost.app/transmission
/home/yunohost.app/transmission → /mnt/disqueVert/yunohost.transmission
/home/yunohost.multimedia/share/Torrents → /home/yunohost.app/transmission/completed
/home/yunohost.multimedia/share/Torrent to download’ → /home/yunohost.app/transmission/watched
```
All links are made with `ln -s` and the `/mnt/disqueVert` disk is an ext4 USB drive.
I hope this can help…

I just opened the log link and found this :
```auto

Can you manually try to change rights on this folder or on any folder inside ?
Can you give us the commands/configuration for your ZFS drive ?
Maybe this could help : [acl [Wiki ubuntu-fr]](https://doc.ubuntu-fr.org/acl) (it’s in french, but there should be other docs in other languages to be sure)

```
Hmm. I never use, nor really paid much attention to these yunohost.multimedia folders. I didn’t do this symbolic link from Torrents. Maybe this is messing things up? Feels like it’s going Torrents → yunohost.app/transmission dir → my zfs drive in one chain. Maybe that’s not good.
What should I do exactly now? Transmission isn’t even installed anymore. Maybe just easier to try a fresh install?

Not sure exactly how to give succinct summary but these details might help. (outputs summarized to the data I think relevant)
```auto
$ zfs list
NAME USED AVAIL REFER MOUNTPOINT
hermes 4.63T 5.23T 89.7G /mnt/hermes
hermes/transmission 160K 5.23T 160K /mnt/hermes/transmission
```
Well, this doesn’t look good. Transmission folder has a number for the user and group. Hmm…
```auto
ls -la /mnt/hermes
total 246
drwxr-xr-x 12 root root 12 Nov 1 20:24 .
drwxr-xr-x 1 root root 34 Jan 17 22:29 ..

OK! I think I found something. I moved some files from my laptop (Bluefin (Fedora Silverblue base)) to Yunohost and I got some errors.
```auto
$ sudo mv Whistle /mnt/hermes/Music/
mv: preserving permissions for ‘/mnt/hermes/Music/Whistle/Whistle/1 - Whistle - Rest In Peace.mp3’: Operation not supported
```
I did some web searches and came up with stuff about ACLs. It says if you have + as a permission those are ACLs. I moved some more files from laptop to test. In the example below, Solomon Burke folder, has an ACL apparently.
```auto
$ ls -la
total 0
drwxr-xr-x+ 1 elias elias 28 Feb 25 15:58 'Solomon Burke'
```
All my zfs datasets have aclmode set to discard. What mode do you have your ZFS set to? I need to research this apparently.
```auto
$ zfs get aclmode
hermes/transmission aclmode discard default
```

I do not use ZFS at all, sorry 😔
I am happy you found something to search for, it looks really like a right management problem 🙂
