I've not only disabled, but removed the configuration information for the proxy in Synaptic. I've checked that there is no /etc/apt/apt.conf proxy information (in fact Synaptic seems to have deleted it). Sadly using aptitude on the command line was also insisting on using a proxy until I rebooted! I can now upgrade things, but not through Synaptic. That's fine by me in terms of being able to use things, but wouldn't be so good for a normal end user, and does leave me wondering what else may be broken. </PRE> </BLOCKQUOTE> If you use proxy or firewall, don't forget to open port 53. It's used by Ubuntu to get update from Repository Server If you use iptable for your firewall, you can open using command below: # ALLOWING DNS to Access to your firewall iptables -A OUTPUT -p udp -o eth0 --dport 53 --sport 1024:65535 -j ACCEPT iptables -A INPUT -p udp -i eth0 --sport 53 --dport 1025:65535 -j ACCEPT Cheers, <TABLE CELLSPACING="0" CELLPADDING="0" WIDTH="100%"> <TR> <TD> Taufan Lubis Registered Ubuntu User #16660 Registered Linux User # 462798 The more you give to others, the more respect you get in return.
