CERTBOT_AUTH_OUTPUT empty for the manual cleanup hook

Help

Hello,

I am trying to update my DNS records using a shell script that gets trigger using the manual-auth-hook param. The same script should also delete the DNS records when the manual-cleanup-hook is triggered.

According to the manual the enviroment variable CERTBOT_AUTH_OUTPUT contains the output “the auth script wrote to stdout”. In my case this variable is always empty and I have no idea why.

I am trying to update the cert using certbot:

sudo certbot certonly --manual --preferred-challenges dns --server https://acme-v02.api.letsencrypt.org/directory --manual-public-ip-logging-ok -d test.de --dry-run --test-cert --manual-auth-hook=/home/pi/./auth.sh --manual-cleanup-hook=/home/pi/./cleanup.sh

In this example I use another shell script for cleanup just to be sure it gets called. Has anyone a solution for this issue?

All I can say is it’s always worked for me…

Maybe there’s a bug in your code? Even a typo somewhere?

Could you post it?

Is the auth script properly outputting things in the first place? Certbot should display the output, and log it, FWIW.

Omg my bad. I thought the variable would contain everything certbot writes to stdout, not the auth script itself. I didn’t return anything, so that’s the reason for the empty variable.

Thanks for your help!
