Time to end this old version. There are newer better appimage versions here:

--------
Edit: - version is now 2.9.9 - everything else applies

Want to keep your existing Gimp 2.8.x and run a Linux Portable Gimp 2.9.9?

Note: This is meant to be used with Gimp 2.8.x - There are dependencies from regular Gimp used by 2.9.9

This works for me in Kubuntu 16.04 64bit.
It should work in other 16.x 64bit 'buntus.  It might work in 14.x 'buntu
It might even work in equivalent version of Mint.
A long shot possibility in other Debian based versions.

Nothing clever, it is assembled using a script and the 'buntu 'gimp-edge' ppa. This updates regularly and I will attempt to keep the following to the current build.

edit: updated 25 December 2017 
Due to updates to GEGL this is only for versions of Ubuntu 16.04 / Mint 18 and later + derivatives
More dependency hell with Ubuntu 18.x versions. This Gimp 2.9.9 appimage is stuck with this release which is Dec 2017
Still very usable, no recent feature additions, just bug fixes

Unzip and run. It will run from your home partition. Same as a regular gimp, first run it creates a gimp profile, in this case ~/.config/GIMP/2.9  It will copy all your resources from ~/.gimp-2.8 so to save a lot of editing, temporarily rename ~/.gimp-2.8 and a new empty Gimp 2.9 profile is created.

First run looks like this.

   

I am not keen on those dark themes, so this is my preference + a shot of one nice addition to Gimp 2.9 - new layer options.  Plenty other new things to explore.

   

Plugins edit: 13 April 2019 updated gmic_gimp_qt version 2.5.6 pre and nufraw v0.42

Some plugins that work. Unpack the zip, these go in ~/.config/GIMP/2.9/plug-ins. Plenty of deprecated procedure warnings annoyance, so I advise running as

A list of very useful things to learn to use in Gimp

Gimp is a very comprehensive piece of software and getting fully acquainted with it is a long process, especially when one is self-taught.

Here is a list of things you should learn to use. Some are fairly basic, but could have been overlooked. Some are pure knowledge, but this helps understanding how Gimp works and why some things are done in strange ways. The order is a bit arbitrary, it's a mix of usefulness (most useful first) and skill level needed. Some of it is more useful for those doctoring photos.

• Basic brush use (photo: Clone/Heal tools)
  
• Image transformations: Scale/Rotate, Color mode
  
• Knowledge: image file formats: XCF, JPG, PNG, GIF, TIFF: differences, uses
  
• Photo: the Crop tool
  
• Knowledge: pixel components: RGB and the "alpha channel" for transparency
  
• Layers, and basic transparency concepts
  
• Knowledge: anti-aliasing
  
• "Exploration" tools: Measure tool, "Pointer" dialog, photo: Histogram dialog
  
• Basic selection tools: rectangle, ellipse, freehand, magic wand, color. Saving selections in channels. Combining selections (add, substract, intersect)
  
• Basic paint tools: Bucket-fill, Blend
  
• Basic filters: Blur/Gaussian blur (photo: "Enhance/Uunsharp mask")
  
• Levels, Curves, and Threshold tools
  
• Basic geometry transform tools: scale/rotate/shear/perspective
  
• Keeping the UI manageable: dockable dialogs
  
• Extending the Gimp: adding fonts, brushes, gradients, plugins...
  
• Using guides, and the Align tool.
  
• Knowledge: Colors: the HSV model
  
• "Quick mask" selection editing
  
• More filters:
  • Map: Bump, Displace
    
  • Render: Clouds, Pattern, Lava
    
  • Distorts
    
  • Noise
    
  • Blur
    
• Advanced transparency control and layer mask
  
• Modes for layers and paint tools: normal, multiply, divide...
  
• Paths (and path editing)
  
• Applying geometry transforms to selection and paths
  
• Creating your own brushes, gradients, palettes.
  
• Writing your own scripts (for those with some programming background)

Paths Basics

This is a short introduction to paths (also known as "vectors") as Gimp uses them.

• Two points called the "anchors" (A1 and A2, below) that are the starting and ending point of the curve.
  
• Two control points called the "handles" (H1 and H2, below), that indicate:
  • Using the line between the anchor and the handle: the general direction of the curve near the corresponding anchor. For the mathematically-oriented this line is the tangent of the curve on the anchor.
    
  • Using the distance between the anchor and the handle: how much the curve follows the direction of the handle.
    

   

   

   

• The whole curve is always inside the convex polygon defined by the two anchors and the two handles.
  
• They are "compatible" with the simpler geometric transforms (a.k.a. "affine transforms") which are those that are found in Gimp's toolbox: shear, rotation, scale, flip(*). Which means that these two sequence of actions are equivalent:
  • "stroke" the curve to create a bitmap layer
    
  • use a transform tool on the layer
    
• and
  • use a transform tool on the curve (in "Path" mode)
    
  • "stroke" the curve to create a bitmap layer
    
• but of course the curve obtained with the second method will be sharper.
  

   

   

   

• Given a stroke like this (the red part is the Bézier curve generated by the closure):
  

   

• Open the stroke by deleting the segment between the two target anchors (2 and 3). These two anchors becomes the start and end of the open stroke. The handles are preserved:
  

   

• Now, reconnect these anchors. The Bézier curve is regenerated, so the stroke shape is the same as initially, but the start and end anchors are the ones delimiting the temporarily deleted segment.
  

   

• This technique can be generalized to have the stroke start on any point. Just add an anchor on the path by Control-licking the path where you want the stroke to start. Then use the technique above, removing and adding a segment that ends on that new anchor.
  

• Using the "Text-along-path" function
  
• Rendering the stroke by painting it with a gradient
  

• One singe stroke for the 'h'.
  
• Two strokes for the "o", the outer outline and the inner hole.
  
• Two strokes for each "b", the outer outline and the inside for the loops.
  
• Two strokes for the 'i', one for the body and one for the dot (a.k.a. "tittle").
  
• One singe stroke for the 't'.
  

• Gimp processes the path as a whole, there is no way to restrict its action to specific strokes.
  
• The path is associated to the canvas, not to a specific layer.
  
• A path can have points that lie outside of the canvas
  
• Coordinates of anchors and handles are not restricted to integer pixels. Sub-pixel paths are possible
  
• Selection from paths where strokes are not disjoint follows an 'even-odd' rule. Starting un-selected from a border, the selection state changes each time it crosses a line. This is neither and intersection nor a union, but a rule that creates the expected selection on text (unless characters overlap).
