Installing hugo as snap on a Ubuntu Core system

support
1

I am using Ubuntu core 16.04.1 and the hugo snap hugo 0.18.1.

To get started with hugo I type: “hugo new site webpage” and the output is (see Output below).

The possibilities to tweak the system are limited in Ubuntu Core. I did the following:

  1. create the directory myself (worked)
  2. use option --force (worked, at least gave no negative result)

But after (2.) the directory “webpage” is empty.

Has anyone any idea?

Well, kind of works in case you install the hugo snap with the option devmode

snap install hugo --devmode

Ok I got even further: --devmode is not required if one connects the right socket with the right plug in the core snap.

I had to do:
snap connect hugo:home :home

Now I have allowed hugo to access my home directory. Nice security feature but I was not aware of it.
