I am posting this question here as the Support section does not seem to be working correctly.
I have installed Joplin on a Windows 10 machine and successfully created notebooks and notes. These are synced to my Synology DiskStation.
My ultimate aim is to convert all of my MS OneNote notes to Joplin notes then run these on Linux machines.
I have Linux Mint installed on a second machine and have installed Joplin on this. The problem I have is that files are not being synced to the DiskStation despite being directed to a drive mapped to the Linux machine.
Joplin is reporting that files are syncing but this is not the case.
Just to check things out on the Linux machine, I changed the sync folder to a local one and this is working okay. However this does not give me what I need.
Any suggestions will be appreciated.
I've moved this to the "Support" category.
Is sync with the DiskStation done through file system sync? If so, and if Joplin was installed as a Flatpak on Linux, then it may necessary to give Joplin access to the DiskStation through Flatseal.
(Note: the Flatpak is community-maintained)
Thanks for the reply.
Just to explain that I am new to both Linux and Joplin so I may not be able to answer your questions fully. The system I used was to map a directory on the DiskStation to the Linux machine using this method:
----------------------------------------------------------------------------------------------------------------------------------
-
Open Files.
-
Click Other Locations.
-
Click your Synology NAS under Networks.

Connecting to a server in Ubuntu 24.04.
- Enter your Synology NAS username and password.
Check “Remember forever” to skip this step with future connections.
The NAS will now be connected and displayed in the sidebar with all the other pinned locations.
--------------------------------------------------------------------------------------------------------------------------------
I then set the sync path in Joplin to what I believed was the correct path:
smb://serenaserver.local/private_2work/ROB/GROUP-03-COMPUTING/SOFTWARE/Joplin/JoplinNotebooks
This is the point where the sync was not working.
However, after posting yesterday, I experimented a bit more and discovered (by using pwd in a terminal) that the path to the shared folder is actually:
run/user/1000/gvfs/smb-share:server=serenaserver.local,share=private_2work/ROB/GROUP-03-COMPUTING/SOFTWARE/Joplin/JoplinNotebooks
With this path entered as the Joplin sync folder, I was able to link the Joplin on my both my Windows and my Linux machines.
As I say, I am new to Linux and understand that there may be better ways to do this. I would appreciate any experienced Linux user's comments on this.
