You unfortunately changed something on your system that broke the package manager's abilitiy to properly use the debian alternatives system.

Setting up plymouth-theme-edubuntu (12.04.1) ...
update-alternatives: error: cannot stat file '/lib/plymouth/themes/default.plymouth': Too many levels of symbolic links
dpkg: error processing plymouth-theme-edubuntu (--configure):
 subprocess installed post-installation script returned error exit status 2

You might want to try askubuntu.com for help as this is not a problem with a package but your particular setup.

Thanks for the info.
This problem occured immediately after restart following upgrade to 12.04.
The bug made it impossible to install, update or remove packages. I have wiped the disk and started with a fresh install of 12.04.
I don't use any of the features of plymouth any more so have no problem not having it installed.
IMO, this is an issue with the upgrade script.
