I restarted the install due to bug #774217, and changed the root partition from btrfs to ext4. This time the same install iso on the same system ran without a problem, so it's definately something triggered by btrfs and not ext4.
While still attempting to install on btrfs, I also ran into this error with package humanity-icon-theme. dpkg gave the following output: (Reading database ... 82240 files and directories currently installed.) Unpacking humanity-icon-theme (from humanity-icon-theme_0.5.3.11_all.deb) ... dpkg: error processing humanity-icon-theme_0.5.3.11_all.deb (--install): unable to install new version of `/usr/share/icons/Humanity/actions/128/stock_media-stop.svg': No space left on device Errors were encountered while processing: humanity-icon-theme_0.5.3.11_all.deb I also attached my syslog from during the install. It contains several tries at running steps of the installer, so it's quite large. ** Attachment added: "syslog-final" https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/873409/+attachment/2636258/+files/syslog-final -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/873409 Title: Ubuntu 11.10 luks+lvm+btrfs install fail To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/873409/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
