Comment 1 for bug 47687

I mounted "/" on a partition that previously had a "/" installed on it.

I did not select to format this partition, and got this error:

Traceback (most recent call last):
  File "/usr/bin/ubiquity", line 130, in ?
    install(sys.argv[1])
  File "/usr/bin/ubiquity", line 55, in install
    ret = wizard.run()

I also had this problem when installing amd64-desktop and not formating the partition on which I chose to mount "/".
