ubiquity can't mount / on xfs

[karl anliot]

i booted to a livecd, and installed lubuntu on a xfs disk by using the manual partitioner.
I used 1 xfs partition to mount /
The operation seemed to compelete successfully, but upon rebooting, all i could see was an error about "serious erorrs were found while checking the disk drive for /."

I managed to muck around in the fstab and fix the /etc/fstab file and the error went away.
I did this by changing the last column in the line that mounts / from 1 to 0
to fix this bug, it should not write to the fstab incorrectly.

That's not a bug in ubiquity. Calling fsck on boot is the correct action for any filesystem; that running fsck on your root filesystem fails indicates either a problem with the kernel's filesystem handling, or a bug in fsck.xfs.

[Brian Murray (brian-murray)]

What you've actually done, by modifying /etc/fstab, is disable the filesystem check for your root partition. It would be helpful if you were to re-enable the filesystem check and boot without 'splash quiet' so that you can see detailed messages regarding the error. Then take a picture of that error and the picture to this bug report. Thanks in advance!

I didn't find any helpful error messages. but i did remember that xfsprogs isn't installed by default in lubuntu, which would cause the error. I'm gonna mark this as invalid.
thanks for your patience.
