Fix error

On error 'Bail out! Gtk:ERROR:gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Icon 'image-missing' not present in theme Rodent (gtk-icon-theme-error-quark, 0)', be sure that '/usr/share/mime' is a symlink to '/opt/share/mime'.

If it is not a symlink then copy the contents from '/usr/share/mime' to '/opt/share/mime'.
Remove the directory '/usr/share/mime'.
Create a symlink with 'ln -s ../../opt/share/mime /usr/share/mime'.
Finally run 'update-mime-database /usr/share/mime'.

Check also the environment variable XDG_DATA_DIRS. Example: XDG_DATA_DIRS="/opt/share:/opt/share"

Outdated - Unity 5 Editor

The Editor of the Game Engine Unity 5 is able to run native on Linux (64-bit). It's not longer required to run it with wine.

On Plop Linux, you have to install PostgreSQL and Node.js to run the Unity Editor.

On troubles, see the file ~/.config/unity3d/Editor.log for more information.

How to install

Download the latest Unity Editor for Linux from the forum thread on the Unity Website Unity on Linux: Release Notes and Known Issues. Currently its unity-editor-5.4.0f3+20160727_amd64.deb.

Download postgresql-9.4.5.tar.bz2 or the latest version from https://www.postgresql.org/download/.

• Install PostgreSQL

tar xfjv postgresql-9.4.5.tar.bz2

cd postgresql-9.4.5

./configure --prefix=/opt && make

sudo make install

cd .. && rm -rf postgresql-9.4.5

Download node-v4.4.7.tar.gz or the latest version from https://nodejs.org/en/download/.

• Install Node.js

tar xfzv node-v4.4.7.tar.gz

cd node-v4.4.7

./configure --prefix=/opt && make
