You can do "sudo dpkg --clear-avail" to get rid of the error you are seeing. But that doesn't explain why the error appeared, most likely some sort of file corruption. And the related bug is not more helpful.
For the failed removal, try to finish the installation with "sudo apt- get install linux-headers-3.0-0" before trying to remove it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/797175 Title: While using synaptic package manager and trying to do an update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/797175/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
