Our solution for now and maybe forever: disabling proxy completely for all ubuntu machines.
Our IT administrators have reviewed the issue and found out that some services from other systems got massive problems with the proxy too. So the conclusion was, to disable the proxy for all machines having massive problems. Far from the best solution, but one that works 100% for now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/797550 Title: indefinite download tries behind a proxy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/797550/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
