I believe I have just run into this same bug while trying to install Kubuntu 6.10. I can reproduce the problem starting with a blank hard drive, and creating three partitions during installation:
/boot using ext2 linux-swap / using xfs Using this layout, it will not let me proceed past the screen where you assign mount points to the partitions; complaining [erroneously] that "XFS may not be used on the filesystem containing /boot. Either use a different filesystem for / or create a non-XFS filesystem for /boot". I am attaching syslog and partman from when I tried this configuration and was prevented from continuing with installation. ** Attachment added: "partman" http://librarian.launchpad.net/6148620/partman -- 6.10 Installer refuses due to xfs https://launchpad.net/bugs/80765 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
