[SOLVED] pveupdate proxmox 5.2-5

normally it is installed in '/usr/bin/pveupdate'
 
there is no automatic update, pveupdate only checks if there are updates available
 
With Proxmox 5-1-46 I disabled update like this:
nano /etc/cron.d/pveupdate
# automatically generated - do not edit
#44 5 * * * root /usr/bin/pveupdate


With Proxmox 5-2-5 I do not find how to disable the script to avoid following error:
TASK ERROR: command 'apt-get update' failed: exit code 100
 
you can deactivate the systemd timer

Code:
systemctl stop pve-daily-update.timer
systemctl disable pve-daily-update.timer
