`linuxdeployqt` is now deprecated by the authors, we are expected to update to the new `linuxdeploy` (without 'qt' suffix) some time in the future.
Download the new tools and unpack the two appimages:
https://github.com/linuxdeploy/linuxdeploy
https://github.com/linuxdeploy/linuxdeploy-plugin-qt
1) Run standard deploy script without the last call to `linuxdeployqt`
2) Run these commands
```
