same problem on gutsy (beta). tried: lsof | grep /var/lib/apt/lists/lock got not output back.
used Shirish Agarwal's ( 2007-06-28 ) solution: sudo killall apt apt-get aptitude and resolved (no reboot/logout were needed). let me know if I can supply any further info. good luck with the final fix! -- Update Manager stops updating from repositories. https://bugs.launchpad.net/bugs/111933 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
