Did you try to pass the AWS keypair trough an environment variable ? I
don't know it that would fix it but it's a 3rd solution, not having access
to the right keys.

I am trying to get duply/duplicity to run. When I execute `duply amazon<br>
backup` in a root shell, all is well. But I want it to be run regularly<br>
by systemd. So I created a service:<br>
<br>
```<br>
systemd.services.duplyamazon =<br>
{<br>
path = [ pkgs.duply ];<br>
environment = { LANG = "C"; HOME="/root"; \
TMPDIR="/tmp"; };<br> script = "duply amazon status";<br>
startAt = "Sat 4:10:00";<br>
};<br>
```<br>
<br>
But when I run that (either by the timer or by `systemctl start<br>
duplyamazon`, it fails with very strange python backtrace:<br>
<br>
```<br>

I think its either because it can not access the tmpdir or because it<br>
can not access the network. And I don't know whether that is because of<br>
some missing environment variables or because of how systemd services<br>
have to be configured.<br>
<br>
Can anyone try to point me in the right direction?<br>
<br>
Thanks in advance,<br>

Arnold<br>

<br>
Background: I am currently setting up a new homeserver with NixOS and<br>
therefore I am moving all the currently running services of my ubuntu<br>
based homeserver. Expect more questions from me in the next weeks… ;-)<br>
