I confirm the bug, and i will try to explain what happened (sorry for my english)
A new customer called me to solve their "server" issues, the server was a fujitsu pc with a freenas installation, because of the limitations of freenas i have done the entire backup of data files and changed disks to bring up a ubuntu 12.04 lts x64 installation. when i have finished to configure everything i got that bug when un- tarring the backup. exactly same error of first post. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/129314 Title: Cannot open tgz archive from FreeBSD To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tar/+bug/129314/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
