Typora not working on Docker

[fjandrad]

First of all, I love typora thanks for the work you have done. I want to extend its use and adding it to a docker image that others will use might help with that.

Setup Description

I build a docker image of ubuntu 18.04 on top of which I install typora.

Command for installing typora with dependencies

RUN wget -qO - https://typora.io/linux/public-key.asc | sudo apt-key add - &&\
 add-apt-repository 'deb https://typora.io/linux ./' &&\
 apt-get update &&\
 apt-get install -y --no-install-recommends \
     libgtk-3-0 \
     libxss1 \
     typora \
     &&\
rm -rf /var/lib/apt/lists/*

Installation seems to be fine, but when I try to open it from the built image I get an error message with a core dumped.

Error message

The error message that I get is

Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted
Trace/breakpoint trap (core dumped)

I do not understand why typora would need this functionality and also how to make it work with Docker. Please help

You can add "--no-sandbox" as launch arguments for Typora >= 0.9.92
