My DietPi is running a lot of stuff, mostly without any problems. So thanks a lot for this great piece of software!
Today I wanted to add Syncthing to my DietPi and got this error:
Configuring Syncthing: backup and sync server with web interface
11:09:43 WARNING: Failed to generate config and keys: mkdir /mnt/dietpi_userdata/syncthing: permission denied
sed: can't read /mnt/dietpi_userdata/syncthing/config.xml: No such file or directory
sed: can't read /mnt/dietpi_userdata/syncthing/config.xml: No such file or directory
sed: can't read /mnt/dietpi_userdata/syncthing/config.xml: No such file or directory
I moved dietpi_userdata to a harddrive after I booted dietpi for the first time (more than a year ago), so it should recognise that the directory was moved. But to me it looks like it didn’t, right? What can I do about this? I’m learning a lot about Linux but users and permissions are still beyond me. I’m lost.
Hi,
many thanks for your report. Which version of DietPi you are running? Pls can you post output of ls -ls /mnt/dietpi_userdata/
I’m running DietPi v6.32.2

looks like /mnt/dietpi_userdata is not owned by user DietPi?? Could that be? That’s way Syncthing is not able to create the directory.
11:09:43 WARNING: Failed to generate config and keys: mkdir /mnt/dietpi_userdata/syncthing: permission denied
Anyway to have it fixed, you can created folder yourselves by running the following as user root:
mkdir /mnt/dietpi_userdata/syncthing
chown -R dietpi:dietpi /mnt/dietpi_userdata/syncthing*
systemctl restart syncthing
Ok, I did that and then reinstalled it with “dietpi-software reinstall 50”. No more error messages, but the web interface is still not working.
Might it still be a problem that the actual userdata is on a mounted drive?
I have two dietpi-userdata folder now, one in /mnt/ and one in mnt/123MYDRIVE123/. Both contain syncthing and syncthing_data subfolders.
dietpi-userdata should be a sym link to your HDD. Did you changed anything on this? Or how did you moved user data to you HDD
No, I didn’t do anything manually. Just pointing to a new drive by using dietpi-drive-manager after launching DietPi for the first time.
pls post entire output of following commands. Don’t cut anything on the output.
ls -la /mnt/
ls -la /mnt/123MYDRIVE123/
ls -la /mnt/123MYDRIVE123/dietpi_userdata/
ls -la /mnt/dietpi_userdata/
root@MediaPi:~# ls -la /mnt/

As you can see on your first output, dietpi_userdata is pointing to your HDD 14BEBE5BBEBE3558
dietpi_userdata -> /mnt/14BEBE5BBEBE3558/dietpi_userdata
You don’t have 2 folder dietpi_userdata because it’s same.
pls restart your system and post output of systemctl status syncthing.service afterwards.
Thank you so much for trying to help me!

ok looks like your Syncthing Gui is LISTEN on local internal interface only.
Okt 08 14:35:52 MediaPi syncthing[649]: [7VQ4O] INFO: GUI and API listening on 127.0.0.1:8384
let’s check configuration file
cat config.xml|grep address
cat: config.xml: Datei oder Verzeichnis nicht gefunden (“file or directory not found”)
Ah sorry my fault, should be following
cat /mnt/dietpi_userdata/syncthing/config.xml|grep address
PS: kein Problem, ich verstehe die Fehlermeldung 
<address>dynamic</address>
<address>127.0.0.1:8384</address>
ok this should fix it
sed -i 's/127.0.0.1:8384/0.0.0.0:8384/g' /mnt/dietpi_userdata/syncthing/config.xml
systemctl restart syncthing.service
So sorry, but web ui stilll does not work. I keep getting page loading error.
ok let’s check if Syncthing is LISTEN on port 8384
lsof -i -P -n | grep LISTEN
might be lsof is not installed on your system. Just use apt install lsof if it’s missing
Doesn’t look like it:
