spacefm 0.9.0-1ubuntu1 (arm64 binary) in ubuntu trusty

 SpaceFM is tabbed file manager with built-in VFS, udev-based
 device manager, customizable menu system and bash integration.
 .
 SpaceFM was developed from a fork of the legacy PCManFM file manager. When
 PCManFM reached version 0.5.2 (aka 'the legacy version'), the original author
 (Hon Jen Yee) abandoned it for a major rewrite which made later versions
 (the 0.9.x series) dependent on gvfs and other components. At about this same
 time, PCManFM-Mod was created as a minor fork of the legacy version which added
 features, addressed bugs, and kept the legacy version alive for those who
 preferred it for its light dependencies and added features.

 Please install spacefm-gtk3 instead if you want to stick with GTK+3.
