This was the bug fixed in partman-partitioning 78ubuntu2 (ubiquity 2.5.11):
partman-partitioning (78ubuntu2) natty; urgency=low * Support archdetect being anywhere in PATH rather than assuming it to be in /bin. It's moved locations in archdetect-deb. -- Mario Limonciello <mario_limoncie...@dell.com> Tue, 18 Jan 2011 13:51:38 -0600 I've confirmed that this is no longer happening on a current Xubuntu i386 daily-live build, and other Xubuntu architectures also seem to have a sufficient version of ubiquity. ** Changed in: ubiquity (Ubuntu Natty) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/705419 Title: ubiquity crashed with ValueError in command(): I/O operation on closed file -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
