Since there are no Duplicati builds for ARM processors on Github, I take it that you are using Docker. Maybe this post could be relevant then:

3

I’m not currently using the Docker build, I’m using the https://updates.duplicati.com/beta/duplicati_2.0.6.3-1_all.deb note that it’s marked as all architecture.

4

Maybe you need to update Mono manually ?

5

Output of mono --version on both the working and broken systems shows they are both running 6.8.0.105:

(mode grasping at straws)
well, there is a slight build difference, the working one is more recent.

(mode desperate)
try to set MONO_THREADS_SUSPEND=hybrid in the Duplicati systemd service configuration. It should be taken in account by adding it in the /etc/default/duplicati file I think.

7

Sure the working build is a more recent build of the same tag, changelog for that version looks like they just removed a desktop file:

mono (6.8.0.105+dfsg-3.3) unstable; urgency=medium

  * Non-maintainer upload.
  * Revert "Added desktop file for mono with and without a terminal window"
    (Closes: #972146)

 -- Salvatore Bonaccorso <carnil@debian.org>  Fri, 09 Dec 2022 14:33:03 +0100

Adding MONO_THREADS_SUSPEND=hybrid in /etc/default/duplicati and restarting duplicati still gives the same error. And I did verify that the systemd unit file includes EnvironmentFile=-/etc/default/duplicati

8

Oh well what remains ? is there enough memory to run Duplicati ? can you do a test using a different backend, the simplest one, the file backend for example ?

9

The rpi has 4GB of ram, which I believe should be enough. And yes, it’s been running the same config but with the file backend for about a week without issue.

10

agree about the RAM. Interesting that basically Duplicati works but not AWS. Is it a networked backend general problem, or specially AWS ? Could you do a quick setup of another networked backend, such as ftp, sftp or webdav ?

11

I should be able to try sftp tomorrow. I do think it’s specific to AWS though as that’s where the stack trace in the log points.

12

It occurred to me that maybe the issue is an architecture specific mono bug that could be fixed in a later version. I upgraded to mono 6.12.0.182 and it’s now working.
