Fix action doesn't fix

[JD-ISWT]

Hey,

I got a problem with the automatic fix action. Seems that the remote action doesn't do anything.
When I acknowledge the problem in the dashboard I have the following message in the logs :

(the acknowledgement was about a single package)

2019-11-07 17:45:03,112 7745 INFO Getting Started with the event: https://monitoring..com/tr_events.php?triggerid=16968&eventid=298 [fix.py:71]

2019-11-07 17:45:03,232 7745 INFO 1

I have also the message on the agent in the log:

1975:20191107:164503.223 Executing command 'sudo apt-get --assume-yes install --only-upgrade sudo'

But the update is not run :

apt-cache policy sudo
sudo:
Installed: 1.8.27-1
Candidate: 1.8.27-1+deb10u1
Version table:
1.8.27-1+deb10u1 500

*** 1.8.27-1 500
500 http://deb.debian.org/debian buster/main amd64 Packages
100 /var/lib/dpkg/status

I checked that the remote commands and enabled on the agent and zabbix user is declared in sudoers

And can I debug the problem and get more traces

Thanks
