Description of my issue

Hi,

I want to backup my Yunohost(YH) instance on my Synology Diskstation (DS).
I created a user (borg-backup) on the DS and added the public key and also installed borg from the community repository. I can access DS with SSH from YH without password.

Repository: ssh://borg-backup@192.168.xxx.xxx:22/volume1/homes/borg-backup

But I alway get this error:

Would be someone so kind and point me in the right direction what I do wrong?
Thanks

In SSH, try sudo chown root:root /etc/sudoers.d/borg

[Bauerbyter]

@tituspijean

udo chown root:root /etc/sudoers.d/borg

Sorry to ask a bit dumb, on which machine?

[tituspijean]

On the one running the backup, I suppose.

Response:

sudo: /etc/sudoers.d/borg is owned by uid 991, should be 0

Zblerg, then let’s try to run su, which will ask for the root password (should be equal to the regular admin password), that will allow to become root

Then chown root:root /etc/sudoers.d/borg

[Bauerbyter]

Thanks, that helped! no more error in services.

Just one more question… I found out, that I have to include the option

--remote-path=/usr/local/bin/borg

to the borg command, but how can I do this in Yunohost?
