I ran into this problem as well. Using a 8.10 Live CD, I booted up Xubuntu and installed dmraid. I went to manual, and tried to install to two partitions (/ and swap) on my stripe. Ubiquity failed with this error repeatedly (and I've reported it at least once.)
I went into Advanced (on the last step) and told it not to install a bootloader and it completed. I'm now going to look for instructions for installing grub separately. -- ubiquity crashed with InstallStepError in configure_bootloader() https://bugs.launchpad.net/bugs/260001 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
