Hi
I have installed Kubuntu Lucid x86 10.4 LTS for the first time. Has anyone got a link that explains how KPackageKit gets the IP address of the repositories? I can install packages using sudo apt-get install xxx OK . KpackageKit tells me I have updates from the repositories. I can select them all and apply , but I get an error that it can't find the repository under a 192.168.100.129:8080 address . Which is not a surprise . I am using mirror.optus.net as a repository and can ping it fine on the command line. So is there somewhere else that KPackageKit maps IP addreses ? I have tried another mirror mirror.aarnet.edu.au and got similar results. My local sub-net is not 192.168.100 and have tried setting fixed IP on the local sub-net and different DHCP addresses and still the same error.

can you post content of source.list

Hope this help

I did manual configuration of the internet connection to isolate any issues there . That got me back to the IP addressing error.
My stateoveride file has

root mlocate 2755 /usr/bin/mlocate
hplip root 755 /var/run/hplip


I don't have gnokii installed.
So I am back for it looking to 192.168.100.129:8080:
for some reason? I have tried 3 different repositories
and it still looks for the same IP address.

I did notice something a bit wacky when I click on the network
manager widget and bring up the connections list and right click to get
properties for the local wired connection the nameserver IP address prints backwards ? Last Octet first and so on.

PS .

Found problem/solution . There is provision a proxy setting in Knetwork manager. This had been set to the 192.168.100.129 address from another network I had used. So command line did not use that proxy so that's why it worked.
