I think that the problem has something to do with my ADSL connection. I’ve tested avast on my two computers PC (xubuntu Dapper Drake) and laptop (xubuntu Edgy Eft) with ADSL modem attached, in both cases everything worked except updates. At the same time I’ve set up a small network, PC conneted to the ADSL modem, the internet connection shared via wireless card, laptop connected to PC in AD-hoc mode.
Now, I that configuration avast on laptop updates ??? What could be the reason, when I’m connected directly to ADSL modem avast doesn’t want to update?
