最佳解决方法
推荐是默认安装的(因为Lucid)。要对特定包进行否定，请使用apt-get --no-install-recommends install pkg。但是，建议不是。您可以使用apt-get -o APT::Install-Suggests="true" install pkg为单个软件包安装安装建议。
没有建议安装conky：
laney@iota> sudo apt-get install conky
[...]
Suggested packages:
apcupsd moc mpd
The following NEW packages will be installed
conky conky-all
……或与建议：
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put将其设置为默认行为
APT::Install-Suggests "true"
在/etc/apt/apt.conf.d/的文件中，例如/etc/apt/apt.conf.d/30install-suggests。
次佳解决方法
对于建议的包，您只需使用--install-suggests标志：
Consider suggested packages as a dependency for installing.
Configuration Item: APT::Install-Suggests.
而不是传递选项-o APT::Install-Suggests="true" [就像你有--install-recommends]
例：
sudo apt-get --install-suggests install mercurial
第三种解决方法
将选项--install-recommends添加到您的命令：
sudo apt-get --install-recommends install virtualbox-4.0
