Octave主目录的快照权限

Question

我昨天安装了octave快照，但是当我运行octave时，它没有访问我的$HOME的权限。如何启用权限？

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

在阅读了https://docs.snapcraft.io/interface-management之后，我认为这是可行的：

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.
