如何检查 apt 存储库？

Question

我正在尝试在 Debian wheezy 上设置 riak。我已按照他们的说明添加了 basho apt 存储库...

$> curl http://apt.basho.com/gpg/basho.apt.key | sudo apt-key add -
$> sudo bash -c "echo deb http://apt.basho.com $(lsb_release -sc) main > /etc/apt/sources.list.d/basho.list"

...并执行apt-get update：

...
Hit http://apt.basho.com wheezy Release.gpg
Hit http://apt.basho.com wheezy Release
Hit http://apt.basho.com wheezy/main i386 Packages
Ign http://apt.basho.com wheezy/main Translation-en_US
Ign http://apt.basho.com wheezy/main Translation-en
...

但是 apt 仍然说没有这样的包：

$> apt-get install riak
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package riak

我怀疑他们的说明可能已经过时，使用的是旧包名称。如何查询 basho apt 存储库以查看它包含哪些包？我想，如果我看到软件包列表，我就可以看到我想要的是哪一个。

您可以使用 aptitude 检查哪些软件包提供了特定站点：

aptitude search '?origin(Unofficial Multimedia Packages)'

p   2mandvd-data                    - Video DVD creator (data files)

或者更糟的是，您可以直接解析包列表：

grep Package /var/lib/apt/lists/ftp.deb-multimedia.org_dists_jessie_main_binary-i386_Packages 
Package: 2mandvd
Package: 2mandvd-data
Package: aac-enc
Package: aacgain
Package: aacplusenc
Package: aacskeys
Package: acroread-debian-files
Package: acroread-fonts-jpn
Package: advancemenu
