Octave 主目录的 snap 权限

我octave昨天安装了 snap，但是当我运行 时octave，它没有权限访问我的$HOME。我该如何启用权限？

ctaggart@rustasia:~/octave-add$ octave
octave: X11 DISPLAY environment variable not set
octave: disabling GUI features

warning: load_path: .: Permission denied
octave:1> ls
ls: cannot open directory '.': Permission denied

看完之后https://docs.snapcraft.io/interface-management，我认为这会起作用：

sudo snap connect octave:home :home
error: cannot resolve connection, slot snap name is empty

description: |
  GNU Octave is a high-level interpreted language, primarily intended for
  numerical computations. It provides capabilities for the numerical
  solution of linear and nonlinear problems, and for performing other
  numerical experiments. It also provides extensive graphics capabilities
  for data visualization and manipulation. Octave is normally used through
  its interactive command line interface, but it can also be used to write
  non-interactive programs. The Octave language is quite similar to
  Matlab so that most programs are easily portable.

答案1

我的机器上没有安装 Octave，因此我使用 Brave 浏览器展示该过程。

  1. 启动软件中心，点击已安装选项卡，从列表中找到八度并单击。 步骤1
  2. 现在，选择权限按钮，从这里您可以为您的应用程序设置必要的访问权限。 第2步
