I'm pleased to say that I've worked around this issue solely by fixing the "sat4j" problem as reported here:
https://bugs.launchpad.net/ubuntu/+source/eclipse/+bug/566131/comments/3 (execute the two "sudo ln" commands) afterwards, I did this: eclipse -clean -initialize rm -rf ~/.eclipse I was then able to proceed with a software update. No more "bundle" problem, no more 503's, no more failure to access download.eclipse.org, etc. I did not have to change my JDK, or use "-vmargs -Djava.net.preferIPv4Stack=true" on the command line, or use a special environment variable. It just worked, on my vanilla Lucid Beta install updated yesterday. -- Unable to access Galileo Update and Discovery sites https://bugs.launchpad.net/bugs/530414 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
