I have made more progress on packaging for linux. There is now a standalone flatpak bundle availalble at this link(
https://drive.google.com/open?id=1o1Xi1W5T8jXh7tB66GtQuoYVx-7Cjius). If you have flatpak installed on your system you should be able to install this with the command
sudo flatpak install slimcoin-qt.flatpak
It is strongly recommended to use this over the bundle I released on saturday as it contains the same binary but is self contained and also removes an issue I found with that bundle in that it does not include the libdb5.3 file. It also provides integration with the system to place slimcoin in the application menu in the window manager. If someone can test this and give me feedback it would be appreciated.
