Synology can't start package


I’ve just installed Duplicati on my DS718+ but I can’t launch the package. I’ve no error message.

Here’s the step of what I’ve done :

  1. Install the “Mono” package from the beta program and it as launch automatically
  2. Install the last Duplicati version manualy
    -> The package was started automatically be I got an error where Duplicati cannot access to the server (something like that).
  3. I’ve stopped it and re launch it. But I’ve never succeed to launch it again…

Here is my mono version :
Rian@RianAS:~$ mono -V

The dir /root/.config :

ash-4.3# pwd
ash-4.3# find . -not -path '*/\.*' | python -c "import sys as s;s.a=[];[setattr(s,'a',list(filter(lambda p: c.startswith(p+'/'),s.a)))or (s.stdout.write('|'*len(s.a)+c[len(s.a[-1])+1 if s.a else 0:])or True) and s.a.append(c[:-1]) for c in s.stdin]"
ash-4.3# cat /root/.config/Duplicati/control_dir_v2/lock_v2 
ash-4.3# ps aux | grep Mono
root     14200  0.0  0.7 1121164 41856 ?       Sl   11:35   0:02 /volume1/@appstore/Mono/usr/local/bin/mono-sgen /volume1/@appstore/Duplicati/Duplicati.Server.exe

I’ve just kill the remaining process (kill -9 14200) and start the Duplicati package from my NAS and now it’s running again but still the same issue :

So I check the Firefox Inspector, and I saw this :

I saw this message in GitHub issue ( so I check and I saw that my admin group ID is the last :

ash-4.3# id -G 'Rian' | cat -e
100 101$

So I’ve added from the Synology user menu a group (add one group, http or other, whatever), you should have this kind of output :

ash-4.3# id -G 'Rian' | cat -e
100 101 1023$

And now it’s working !
