Debian

###Official Packages Official Debian packaging of SpaceFM and udevil is reportedly underway. You can provide encouragement here and here.

###Self-Building Packages Additionally, self-building deb packages for all Debian-based distros (Lenny and later) are available in Downloads for SpaceFM and udevil (to save a file, click on its filename and click 'View Raw'), and are also available via the author's PPA as spacefm, spacefm-gtk3, spacefm-hal, and udevil. These convenience deb packages contain the source code and require SpaceFM's build dependencies, and $TMPDIR (usually /tmp) must NOT be mounted noexec.

###Build A Binary Package Or easily build your own binary deb package from source using the instructions in the README.

###For Debian Squeeze If you have trouble installing libgtk2.0-dev, you may need (from Crunchbang forum):

sudo apt-get install -t squeeze-backports libgtk2.0-dev

(does this fix only apply when using Crunchbang backports?)

###Ubuntu From Issue #49:

If you want to have the menus in view from the 'dash' launcher in Unity you need to do the following:

cp /usr/share/applications/spacefm.desktop ~/.local/share/applications/
gedit ~/.local/share/applications/spacefm.desktop

Then edit the Exec= line in that file to:

Exec=env UBUNTU_MENUPROXY= spacefm

Note some other Unity issues, most with workarounds.

###Lubuntu Mateusz Łukasik's PPA provides SpaceFM packages.
