Package is broken

I have the same bug as in this thread (that I started) :

http://forum.avast.com/index.php?topic=28488.msg232662

Same server, same error, same file who bugged… but 1 year later. I don’t want to reinstall the ADNM for the fifth time (this doesn’t solve the problem).

Does anyone have a solution for this ? Proxy disabled, but no connexion to internet (long long timeout, 5min), avast’s downloads servers are in a whitelist in squid/squidguard.
