This problem occurs imediate after the fresh installation of the Sabayon 3.5, only after their further automatic updating It
Sabayon is very recently installed...
If Yes, i have in mind that is because the Entropy installer removed the list of portage packages for mantain further compatibility of Portage and Entropy...
If this, try the commands, in order:
su and your root passw.
emerge --sync (for syncronize Portage)
emerge portage (updating portage)
emerge layman (updating overlay control)
layman -d sabayon (remove sabayon overlay)
layman -a sabayon (add sabayon overlay again)
layman -s sabayon && layman -S (updating sabayon and existing overlays)
emerge -va equo entropy spritz ( for updating Entropy, their command and GUI)
equo update (for updating equo list)
equo database gentoosync ( for syncronize Entropy System with Portage)
after running all these commands, please try to emerge a simple packages, as amsn
You may also see documentation about these wolfden procedures
in the Wiki of Sabayon, for this see Portage and Entropy Installers.
