如何翻译通过 snap 包安装的程序？

Question

我在 Ubuntu 16.10 Yakkety Yak 中通过 snap 包安装了 VLC。但是安装是用英语完成的（我的 Ubuntu 版本是西班牙语）

基本上在Snap (snapcraft?) 和翻译的应用程序以及它如何更改 vlc (snap) 中的语言以及 VLC 的翻译文件中提出了相同的问题：

Answer 1

对于打包为快照的应用程序，可能需要对代码进行更改，以便它可以在文件系统中的正确位置找到翻译。

对于使用 gettext 的应用程序和库，这意味着调用bindtextdomain()需要将环境变量的值添加$SNAP到作为第二个参数传入的目录路径中。任何不执行此操作的应用程序（和/或它们可能使用的库）实际上可能没有有效的翻译，因为使用的硬编码路径指向快照之外的路径。

Answer 2

正如ToX 82在Snap (snapcraft?) 和翻译应用程序的评论中指出的那样，有一个错误报告。毕竟，这似乎不是单个 VLC 快照的问题，而是一般快照本地化问题。
