Package: monitoring-plugins-basic
Version: 2.4.0-3+deb13u1
Severity: normal
File: /usr/lib/nagios/plugins/check_apt
X-Debbugs-Cc: ukleinek@debian.org

Hello,

I currentently experience:

	root@quarterberry:~# /usr/lib/nagios/plugins/check_apt
	APT OK: 0 packages available for upgrade (0 critical updates). |available_upgrades=0;;;0 critical_updates=0;;;0
	root@quarterberry:~# apt list --upgradable
	linux-image-arm64/stable-security 6.12.86-1 arm64 [upgradable from: 6.12.85-1]
	Notice: There are 2 additional versions. Please use the '-a' switch to see them.

and so icinga doesn't notify me about the pending upgrade.

I would expect that check_apt detects that as a critical update.

Best regards
Uwe
