After some more digging around, it looks like this is a proxy config issue. I found that apt proxy setting was completly wonky:
cat /etc/apt/apt.conf Acquire::http::Proxy "http://http://web-proxy.britain.agilent.com/:8088/"; If I delete or fix this then everything is okay. I *think* this must have been automagically set by something when I first installed Hardy on my PC. The only question is should the update manager check that the source it's using for proxy information is in the correct format before deciding to use it? -- update-manager crashed with InvalidURL in _set_hostport() https://bugs.launchpad.net/bugs/283155 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
