[Bug 1361914] [NEW] Ubiquity offers to erase existing OS rather than use entire disc even when more than one disc exists

[Erick Brunzell]

Public bug reported:

In comparison to bug #1265192 this is a minor issue but I felt I should
report it anyway. I'm testing Ubuntu GNOME Utopic Beta 1 candidates and
noticed with a simple two disc setup where Trusty resides on one disc
and the other disc is bare I get no entire disc option but rather just
erase Trusty. But the button said Continue rather than Install now so I
took the bait and the next screen does offer the choice of selecting
either the 160GB drive where Trusty resides or the blank 80GB drive.
I'll attach a screenshot of the options offered. I did abort the
operation because I'm too busy to restore my backup if things should go
awry.

Here's the output of parted -l:
