Both Jeremy Bicha and I encountered a new ubiquity bug while testing the Beta 2 candidates:
As you can see there it really only effects the "install alongside" option, but it's kind of hard to explain, and it's already been suggested that it may be a duplicate of this:
I'm fairly certain that it's not a dupe so I'm stealing some electronic ink to post some screenshots for comparison with Lubuntu RR Beta 2 images. In both cases I started with a very simple setup:
In both cases you need to simply select "Install alongside":
lubuntu@lubuntu:~$ sudo parted -l
Model: ATA WDC WD800JB-00JJ (scsi)
Disk /dev/sda: 80.0GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
1 1049kB 77.9GB 77.9GB primary ext4 boot
2 77.9GB 80.0GB 2137MB extended
5 77.9GB 80.0GB 2136MB logical linux-swap(v1)
Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0
has been opened read-only.
Error: Can't have a partition outside the disk!
Then with Lubuntu things work as expected, you're presented with the option to resize as you wish, and Install now is active:
Then after clicking on Install now you're asked to confirm:
But with Ubuntu GNOME only the Quit button appears to be active and you're not able to advance beyond that screen:
After waiting and waiting for a long time clicking on Quit does not even appear to do anything but if I click on the X in the upper right-hand corner I do get this:
Hopefully my pics will be worth a few thousand words.
