Release version for Ubuntu 18.04 crashes #78

Closed frederik-elwert closed 5 years ago

frederik-elwert commented 5 years ago

When trying to launch the released binary for Ubuntu 18.04 (v0.1.6), the application crashes and I get this output:

Interestingly, I get the same error when trying to install/launch the app using the source release and pipenv.

Almost the same error with current master. But now I also get an NSS error:

Thank you for this bug report. Both error messages are related to PyQt5 (or more precisely: Chromium), whose web engine is used to render the UI. The UI itself is built with web technologies (basically Flask and some JavaScript), so the PyQt5 component is more or less optional (but actually wanted for the desktop application feel). We are currently working on v2.0 with some general improvements (release will be definitely in 2018), hopefully fixing this one too. Until then you could use your default browser to render the UI (= running the app).

TL;DR As a workaround, you could run the application from source with:

$ python topicserxplorer.py --browser

which will launch the app in your default browser.

v2.0 has been released. This error should no longer occur, if it does, please open a new issue. Thank you!
