Thanks for the "workaround" Stefan Tauner. I am (still) in the process of upgrading a whole bunch of machines from 12.04 to 14.04, and out of 8 boxes so far only one has displayed this behvaviour - your workaround worked a treat.
The interesting bit (for me, anyway) was that 6 of the machines were cloned of the same VMware template, and one of those 5 so far was the only one misbehaving. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1168518 Title: "The value 'precise' is invalid for APT::Default-Release" when upgrading from precise to quantal via command line To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1168518/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
