I think I have summarized the problems related to user-callback script error handling in this issue: https://github.com/bit-team/backintime/issues/827 I also described the (huge) work to do to improve this. @c.buhtz Perhaps you can add above link to the debian bug report as "known issue" I cannot see any simple workaround for this. A possible workaround would be to add try/catch functionality to the user-callback script and send emails in the catch part (hoping this does not cause another error ;-) https://www.xmodulo.com/catch-handle-errors-bash.html On Fri, 2023-01-20 at 12:25 +0100, Michael Büker wrote:
Hi,
from my incomplete knowledge, I'd say that cron sends an email when a process it calls terminates with an exit code =! 0, or prints any output to stdour or stderr.
So this sounds like the backintime process called from cron does not terminate =! 0 and does not print anything when its user-callback script fails. I can see that this is irritating, and contrary to expectations.
We've had a related complaint before: https://github.com/bit-team/backintime/issues/1053
We'd probably need to examine if/how the exit code of the user-callback script gets handed back to the backintime process (and then to cron), or why this does not happen.
Cheers, Michael

Hey folks,
can someone please who knows good about cron have a look at this bug report. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=985260
The users expect that he would got a mail if there is a syntax error in one of his user-callback scripts running by cron.
I'm not sure if this should be the default behaviour and which component is responsible for sending mails. For the letter I assume cron should do this.
So I assume this bug is not related to Back In Time. Am I wrong?
