例子：

1. 我可以安装一个名为“ libreoffice”的快照包，但此命令未列出该软件包：“ sudo snap find”

2. 有一个名为“ telegram-sergiusens”的软件包，也可以安装，但未列出。

如何列出所有包裹？

请注意，不需要sudo。snap find并snap install会工作得很好，没有它。

snap find仅在稳定频道中显示升级和公开快照。通过以这种方式管理快照，用户可以期望在snap find用于应用发现时达到一定程度的质量。

如果您想知道所有存在的快照，请尝试使用uappexplorer：

$ snap install uappexplorer-cli
$ uappexplorer-cli --type snap

1. 安装SnapWeb，这是“用于快照管理的美观实用的界面”

   sudo snap install snapweb
   

2. 使用您选择的浏览器转到http：// localhost：4200。

请享用。

上面建议的命令仅显示可用快照的一小部分

~$ uappexplorer-cli --type snap

要使用上面的命令捕捉行数：

~$ uappexplorer-cli --type snap | grep '│' | wc -l
31

只有31个快照？

我想出了另一个命令，它显示了更多的可用快照列表

~$ sudo snap find $

但是我不确定这是否真的是所有可用的快照

~$ sudo snap find $| wc -l
101

要么

~$ sudo snap find .| wc -l
101

或％-，öäü等其他很多...显示（仅）101个可用的快照2016-02-14

它没有记录，但是快照列表保存在文件中/var/cache/snapd/names（根据Alan Pope，它包含稳定通道中的所有已知快照）。如果您对可能丢失稳定通道中不可用的一些快照以及默认快照存储中不存在的快照感到满意，则可以手动检查该文件以查看可用的快照。

我认为您也可以通过向发送请求来直接查询存储https://api.snapcraft.io/api/v1/snaps/names，但尚不清楚所需标头的正确值是多少，并且它的速率受到很大限制。而且，/var/cache/snapd/names无论如何，它似乎都会返回严格的可用名称子集，因此最好查看该文件。
