今天早上我收到了来自 Ubuntu Landscape 的以下电子邮件:
The following security upgrades are available:

php7.2-xml 7.2.24-0ubuntu0.18.0 USN-4239-1
但在 VPS 上(使用 Ubuntu 18.04.3 LTS)其中安装了 Ubuntu Landscape,执行完后apt update
,我收到了消息All packages are up to date
。
完整的输出是:
# apt update

apt-cache show php7.2-cli
报告称,安装的版本是7.2.3-1ubuntu1
,确认此软件包没有更新至7.2.24
。
您认为有什么解释吗?谢谢
