Issue Planified Task not working anymore after upgrading Debian/updating Plesk

[Kouenteen]

Server operating system version

Debian 12.12 (and Ubuntu 24.04.3 LTS)

Plesk version and microupdate number

Obsidian 18.0.73

Hello.

Quick summary :
I upgraded a Debian 10 server to Debian 11 and then to Debian 12 using this Plesk documentation : https://support.plesk.com/hc/en-us/...-upgrade-procedure-on-Linux-server-with-Plesk

While the server was on Debian 10 with Plesk in 18.0.70, there was a planified task on one website that previously worked.


wget -q -O - "https://domain.tld/module/gsitemap/cron?token=297d9f7x6q3&id_shop=1"

After upgrading to Debian 12, I updated Plesk from 18.0.70 to 18.0.73.

At first, there was some dependencies issues :

wget: error while loading shared libraries: libnettle.so.8: cannot open shared object file: No such file or directory

I have resolved them by copying all wget’s dependencies into the lib/x86_64-linux-gnu folder of the website.

cp `ldd /usr/bin/wget | grep "=>" | awk '{print $3}'` /var/www/vhosts/domain.tld/lib/x86_64-linux-gnu

After that, the error changed into :

The task "wget -q -O - "https://domain.tld/module/gsitemap/cron?token=297d9f7x6q3&id_shop=1"" completed with an error in 0 seconds.

The task was and is still configured at the website's level (Domains > domain.tld > Development Tools -> Planified Task).
By going into the Tools & Settings menu, then in Tools & Ressources > Planified Task > Settings, the crontab's shell is selected on /bin/bash (chrooted).

It seemed odd to me that there was no error detail anymore from the task scheduler. So I looked into the following log file and got this error right after executing the task :

cat /var/log/plesk/panel.log

I tried to create a new website and then executing the same planified task, same error. I did plesk repair installation/all, nothing.
Even tried on another Plesk server that I upgraded from Ubuntu 20.04 to 22.04 and then 24.04, same error.

Maybe someone has an idea of what could possibly be wrong ?
I could provide more logs if necessary.

Kind regards,
