我已将 Kali 2019.4 安装到 Virtualbox 机器（4GB、2-CPU）中，并进行了全面更新和升级。
我正在尝试以 root 身份直接从 Kali 存储库 (apt install openvas) 安装 openvas，但无法完成安装过程。
下载并解压后，在“处理”阶段（约 97%），安装出现以下错误：
<...>

如果我检查“/tmp/tmp.dqbpol09MD/openvas-manage-certs.log”，我会得到：
Generating a 3072 bit RSA private key...
configFileLoad: No such file or directory
Error loading template: /tmp/tmp.dqbpol09MD/caopenvas-cert.cfg
检查“/tmp/tmp.dqbpol09MD/caopenvas-cert.cfg”，我有：
expiration_days = 3652
country = "DE"
locality = "Osnabrueck"
organization = "OpenVAS Users"
unit = "Certificate Authority for kali.' " ' ' "
ca
cert_signing_key
crl_signing_key
但在这里我不知道该检查什么......
国家和地区是错误的（我来自爱尔兰）但也许它们是默认值。
看起来“unit”、“ca”、“cert_signing_key”和“crl_signing_key”没有设置，但也许那时安装被中断了。
我需要检查什么？问题似乎与证书创建有关，我可以在安装之前创建一个证书并将其传递给安装程序吗？
谢谢
编辑
我重新安装了机器，这个问题不再出现。这次我使用官方 ISO 而不是官方 vagrant 文件安装了 Kali，也许这就是问题所在。
