Can't update 8.6.0

[Anju Bala]

Hello everyone,

I have Plesk 8.6.0 installed and several update are still pending:

Base packages of Plesk 8.6.0-debian4.0.build86080722.01 Oct 1, 2008

and

Plesk Panel 9.0.0
Plesk Panel 9.0.1

But I can't install the said "Base packages of Plesk 8.6.0". It gives me the following mail "Autoupdate failure report":
