problem with adept on kubuntu 7.10 amd64

[wdrwc]

I have just installed kubuntu 7.10 amd64 and I have a problem with adept.
Every time I try to upgrade or install a package I get the message:

Could not commit changes - Adept Manager
There was an error commiting changes. Possibly there was a problem downloading some packages or the commit would break packages.

but packages get installed.

Is it a problem with the configuration of my system?
I would appreciate any suggestion.
