Sorry, I read your post too quick, I thought you were using the duplicity nixos module, not duply. How are you running duply ? In a terminal ? In a systemd service ? In a cron job ?
Eventually i want to run it as a cron job but the error i described occurs when running it in the terminal. I ran it there to see if everything is working as intended.
I tried this just to see if it helps somehow, but i don’t want to run it like this eventually:
Yes, duply works with my local backup (where it doesn’t have to use ftps), so duplicity must also be working, as duply is just a frontend. It prints some errors but is still working, maybe the .nix wrapper is not correct?
Let me show you 3 Screenshots, maybe this is helpful:
Sorry, i didn’t think of running duplicity without the wrapper.
It shows this:
~ ❯ duplicity /home/sperber/Downloads ftps://username:userpasswd@server.net//test
LFTP version is 4.9.2
Attempt of list Nr. 1 failed. BackendException: Error running 'lftp -c "source /tmp/duplicity-uwg2_bqw-tempdir/mkstemp-laswiouj-1; ( cd /test/ && ls ) || ( mkdir -p /test/ && cd /test/ && ls )"': returned 1, with output:
cd: Fatal error: gnutls_handshake: An unexpected TLS packet was received.
mkdir: Fatal error: gnutls_handshake: An unexpected TLS packet was received.
So, something is up either with lftp or some encryption service.
Btw, how can i delete all the files downloaded / installed during this after we are finished trying it out? I’ve never used nix-shell before and it downloaded close to 3GB.
@symphorien i’m still having the issue with missing lftp. I’m on 22.11 and have duply installed as a system package. Using duply from unstable also shows missing lftp.
Your fix solved this problem when i tested it though and i thought that it would now also be solved if i use the package from the Nixos repo.
Am i missing something?
For reference, here is the output of duply from just now:

Right… If i add lftp to my system packages, it works. I thought you added it as a dependency for duply as you mentioned something about making it work out of the box.
