Installing Environmental Visual Enhancement can produce CKAN.TooManyModsProvideKraken.
I can install all of these mods by following a different method. Installing scatter first helps. However I suspect that most end users will do this instead.....

1. Enviromental Visual Enhancements
Asks for config choice
-EVE config
-SVE High
-SVE low
-SVE Medium

2. Select SVE High
Asks for sunflare config
-Scatter sunflare
-Astroniki
-Cepheus
-Eden
-SVE sunflare

3. Select Astroniki

Apply changes
Which lists mods to be installed as
EVE 2EVE1.2-2
SVE Highres 2:1.1.6
scatter 2v0.0300
SVE Scatter config 2:1.1.6
Astroniki for scatter 1.2

5. Click on apply
Recommends Planet shine
Tick mod

6. Click continue
Throws exception

CKAN.TooManyModsProvideKraken: Too many mods provide Scatterer-config:

Further Research.
Installing scatter first before going through the steps avoids problems.

Have confirmed that if Scatterer is selected first. All the same config files appear for selection and install is completed. Whilst doing it as above breaks things.

First posted as a possible NetKan issue. Asked to move here by @politas. Just keep everything in one issue report that one has been closed and last comment moved here.

This is a code issue. Looks like we aren't staying aware of all the changes as we traverse levels of dependency.Can you re-open this as a main repo

Many thanks

I believe this was addressed in #2577. Main.InstallMods now catches TooManyModsProvideKraken and prompts the user to choose.

CKAN/GUI/MainInstall.cs

Lines 175 to 198 in 7413c23

	catch (TooManyModsProvideKraken k)
	{
	// Prompt user to choose which mod to use
	CkanModule chosen = TooManyModsProvideCore(k).Result;
	// Close the selection prompt
	Util.Invoke(this, () =>
	{
	tabController.ShowTab("WaitTabPage");
	tabController.HideTab("ChooseProvidedModsTabPage");
	});
	if (chosen != null)
	{
	// User picked a mod, queue it up for installation
	toInstall.Add(chosen);
	// DON'T return so we can loop around and try the above InstallList call again
	}
	else
	{
	// User cancelled, get out
	tabController.ShowTab("ManageModsTabPage");
	e.Result = new KeyValuePair<bool, ModChanges>(false, opts.Key);
	return;
	}
	}
