Attempt to change bootsplash screen in Maui linux shows authentication error - prince - 23rd May 2017

I am using Maui Linux 17.03. I am trying to change the plymouth boot splash screen to solar theme. I go to 'System Settings->Startup and shutdown->Boot Splash' and I select solar theme then apply. It asks for password. But when I hit ok after providing password it shows

Code:
Unable to authenticate/execute the action: 2, update-alternatives returned with error condition 2.

I tried to change it by editing /etc/plymouth/plymouthd.conf file. But it doesn't change. Boot start up splash stays at default maui theme. However when I shut down I see solar splash screen.

Why am I getting the authentication error?

And since changing plymouthd.conf doesn't do anything where the OS pulling the information of which theme to use?

The system uses the update-alternatives system to set the default.plymouth theme.
So editing the plymouthd.conf won't change a thing.
Also plymouth is put into initrd so it needs update-initramfs -u run as root aswell.

The authentification failure is basically a problem with update-alternatives command execution.
We'll investigate into it.

Update: Turns out to be an upstream bug. Reported it here with a proposed fix: https://bugs.kde.org/show_bug.cgi?id=380113

As workaround for now just make solar known to update-alternatives by executing in a terminal

Code:
sudo update-alternatives --install /usr/share/plymouth/themes/default.plymouth default.plymouth /usr/share/plymouth/themes/solar/solar.plymouth 100

After that the Boot Splash configuration should work setting solar.

Netrunner did not show this problem. So this must be specific to Maui.

It isn't specific to Maui. Netrunner shows the same issue but without the error message.
So basically on netrunner changing the splash does not change the update-alternatives from the defaults.
I am currently not sure why the error message isn't shown. Maybe its an earlier version of the kcm without error handling.
