I’m running Duplicati 2.0.5.1_beta_2020-01-18 on Ubuntu 20.04 on a tinkerboard. It has been working for for quite some time. However recently I’ve been getting crash messages in my system log. It appears to be crashing while constructing email messages. I’m running a local Postfix mail server and that is working fine for other applications.
My options are
--send-mail-level=Warning,Error,Fatal
--send-mail-subject=tinker: Duplicati %OPERATIONNAME% report for %backup-name% - %RESULT%
--send-mail-to=user@somehost
--send-mail-url=smtp://localhost:25/?starttls=never
The system crash log is here
