Uninstalling does not remove crontab entry

[Responseless]

Uninstalling does not remove crontab entry so errors occur after removing.

emails sent include:
bin/sh: 1: /root/Proxmox-Updater/check-updates.sh: not found

Sad to here, that you want to uninstall.
How did you uninstall?
A little backgroud; the installer make a backup from your crontab file. Then, the uninstaller delete crontab file and restore the backup file.
Could you please gave me the output from find /etc/crontab*

EDIT:
checked the code now. You are right. The "restoring" part is missing in code.
I will fix that.

Could it be, that you skip welcome screen uninstall during uninstall?
I think that would cause the issue ;)
