Ubuntu partition probably not used

Question

I have 3 partitions in Ubuntu and I am trying to install Anaconda, that is pretty big, but my hard disk is 500GB. I receive an error saying that there is no space in my drive. I explored partitions and it seems the biggest partition /dev/sda3 is not mounted or anyway it seems is not used (not appearing in df).

How can I start to use /dev/sda3 and continuing to work in my home directory?
Could you please clarify my partition situation?
Where all my application have been installed until now?

Thank you.

I believe you did not add sda3 to the volume group. So you'd need to:

Extend your volume group to include sda3 ("ubuntu--vg" is the volume group):

vgextend ubuntu--vg /dev/sda3

Check the new size of your volume group:

vgs

Extend your logical volume to the entire volume group space ("ubuntu--lv" is the logical volume):

lvextend -l 100%FREE /dev/ubuntu--vg/ubuntu--lv

Check the new size of your logical volume:

lvs
