Hello salimHydro,

My name is UnloosedCake, and I'm here to help you with this issue!

If you're running the OS off of a certain partition, you cannot unmount/resize that partition while the OS is turned on. You'd have to hook up the hard drive to another computer and resize it there, but that could cause boot issues. 

 

Have you tried going through the installation process a second time, and just completely wiping and re-partitioning the drive? As long as you don't have any important data there, that'd be the easiest way to make sure Ubuntu works with the partition.

 

-------------------------

 

If these steps don't work, I have a few questions to hopefully get the right solution:

- How many partitions are on the physical hard drive?

- How is the OS installed? Is it running off of the hard drive itself? CD? Thumb drive? 

- Are you running a 'live' version of the OS or is it fully installed? (Do your settings revert to factory ones each time you restart the computer?)

- Can you post a screenshot of the message you're receiving when the issue occurs?

try few things here:

you obviously have a swap partition along with your lvm2 partition right

do the swapoff command

sudo swapoff -a

 

if this didn't work use the logical volume management tool for the the partition from the Live CD
