Ubuntu 16.04.1 LTS: file manager is not native so it does not show USB drives

[evpo]

Qt falls back to its own file manager that does not integrate with the system and does not show usb drives. See the description here

The issue is a known Qt problem. Qt 5.7 GTK2 plugin libqgtk2.so is missing from the installation because they moved to GTK3 and didn't package GTK3 either.
The bug has been reported here

This is really an issue - it took some time to figure out why the native file dialog is not shown anymore with Qt 5.7 under Linux Mint 17.3.
I suggest to give others an official hint about this.

They think that the problem will be fixed in Qt 5.8 that should come out in November.

One option to make it work is to use AppImage.

Shouldn't be hard to do, especially given that this project is already building on Travis CI. See linuxdeployqt and especially the Travis CI examples linked there. Basically linuxdeployqt -appimage can do it automatically for you.

Thanks for you help. I have already built an AppImage from the webupd8 package with help of your yml and tested on Ubuntu 16.04. I can see a native file dialog. It is a bit different but still better than nothing and it will work for most users.

I will look at linuxdeployqt and probably make an official AppImage shortly.
