How to Increase the size of my Root Logical Volume in a partition?

Question

I had to encrypt my Ubuntu for my job, but I also had to keep my dual boot due to some softwares that I absolutely need and can only run on Windows.

With that, I followed the instructions from here and here, which were very thorough instructions. However, when finishing my installation, I had very little space on my Linux partition.

I have a 1TB hard drive, where I set 400GB to Windows and 530GB to Ubuntu. However, when I checked, my Ubuntu has only 8GB of space, when I expected it to have 530GB

When I ran

$ sudo fdisk -l

I received the following result, where the key parts are here

Disk /dev/mapper/CryptDisk: 531.1 GiB, 570299514880 bytes, 1113866240 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes


Disk /dev/mapper/vg_ns-ns_root: 7.5 GiB, 8053063680 bytes, 15728640 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes


Disk /dev/mapper/vg_ns-ns_swap: 1 GiB, 1073741824 bytes, 2097152 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

And this is what it shows on GParted, where the /dev/sda5 is the partition where I put my Ubuntu. GParted Image

I know people may have asked this before, but nothing seems to be working for me. How would I make it such that my Ubuntu does end up using all of the 530GB?

Thank you very much!

I found Tecmint's guide to do so. I guess I didn't know what to search for.
"How to Extend/Reduce Logical Volume Management"

Since the partition is encrypted, a lot of the commands had to be run as a super-user, but besides that, it works!
