Hi all,

I installed the Freespace 2 "Knossos" on Ubuntu MATE 20.04 launcher according to this:

sudo apt-get install nodejs npm python3-wheel python3-setuptools pyqt5-dev pyqt5-dev-tools qttools5-dev-tools qt5-default curl
sudo apt-get install python3-pyqt5.qtwebengine python3-pyqt5.qtwebchannel python3-requests-toolbelt python3-ply

sudo apt update && sudo apt install yarn
pipenv install
yarn install
sudo dpkg -i *.deb

When running Knossos I receive the following error when installing retail campaigns:

Sorry, this bugreport is not useful without a stack trace.

Please follow the instructions on https://wiki.ubuntu.com/DebuggingProgramCrash and try to get a stack trace.

Alternatively, a small example how to reproduce this crash would be useful. E.g. and HTML file, an URL and/or a C++ program using Qt WebEngine.

Hi,

thanks for answering.

During handling -not playing- that error occurred also saying that I don't have enough memory for a report (8 GB here). Meanwhile, I use Ubuntu 20.04 and after the latest updates the error didn't occur after I reinstalled Knossos.

Before that update I also had severe problems with the update-notifier packages "-gdm" and "-dbus", bit I don't think that is connected somwhow, is it?

"but" not "bit"

[Dmitry Shachnev (mitya57)]

No, it should not be related to anything -gdm or -dbus. As you say it doesn't occur now, I will better close it.
