Comment 1 for bug 50833

Could you please attach /var/log/installer/syslog, /var/log/syslog, and /var/log/partman to this bug, using the "Add Attachment" link on the bug's web page? Thanks in advance.

At present, you must reformat system partitions (e.g. /, /boot, /usr, or /var) during installation; bug 47046 is filed to note that the partitioner should warn you about this up-front. If you are upgrading an existing installation, then please see http://wiki.ubuntu.com/DapperUpgrades rather than using this installer.
