Answer 1

推荐是默认安装的（自 Lucid 起）。要为特定包否定这一点，请使用apt-get --no-install-recommends install pkg. 然而，建议并非如此。您可以使用apt-get -o APT::Install-Suggests="true" install pkg.

在没有建议的情况下安装 conky：

laney@iota> sudo apt-get install conky
[...]
Suggested packages:
  apcupsd moc mpd
The following NEW packages will be installed
  conky conky-all

……或建议：

laney@iota> sudo apt-get -o APT::Install-Suggests="true" install conky
[...]
The following NEW packages will be installed
  apache2 apache2-doc apache2-mpm-worker apache2-suexec apache2-utils apache2.2-bin apache2.2-common apcupsd apcupsd-cgi apcupsd-doc ario ario-common conky
  conky-all icecast2 ices2 libao-common libao4 libaprutil1-dbd-sqlite3 libaprutil1-ldap libcue1 libmpdclient2 libresid-builder0c2a libsidplay2 libsidutils0
  moc moc-ffmpeg-plugin mpd

您可以通过将其设为默认行为

APT::Install-Suggests "true"

在一个文件中/etc/apt/apt.conf.d/，例如/etc/apt/apt.conf.d/30install-suggests。

Answer 2

对于建议的包，您可以简单地使用--install-suggests标志：

将建议的软件包视为安装的依赖项。
配置项：APT::Install-Suggests。

而不是传递选项-o APT::Install-Suggests="true"
[ 就像你一样--install-recommends]

例子：

sudo apt-get --install-suggests install mercurial

Answer 3

将选项添加--install-recommends到您的命令中：

sudo apt-get --install-recommends install virtualbox-4.0
