Mqtt Explorer doesn't start on Ubunt 20.04

[mygitus]

Installed the app from Ubuntu Software (Ubuntu 20.04). On opening the app from the application launcher, nothing happens. Please forgive me if I am missing something really obvious... I also had the same issue on Ubuntu 18.04.

Works for me on KDE Neon(based on ubuntu 20.04) - I used application image 0.4.0-beta1

same issue for me ubuntu 20.04 and on gnome.
mqtt-explorer does not start, running in console does not show any output but instead the process ends right away.

EDIT:
running strace mqtt-explorer shows write(2, "need to run as root or suid", 27need to run as root or suid) = 27 however running via sudo also fails due to /run permissions.

Thx for the report I'll check it out.
You did install it via snap?

I am having a similar issue. mqtt-explorer will run once but then no more. Removing the snap and reinstalling then works again for a single run.
