I was running 18.04 LTS on a 320GB hard drive on a fully encrypted install and I recently upgraded to a 1TB hard drive. I made a disk image on my external drive and restored the system on to the new 1TB drive. After restoring, I attempted to expand the partition using gparted to the full disk size but was unable. After doing some research, I found that gparted does not allow you to manipulate encrypted partitions so now I’m in search of a way ahead. Can anyone help me with step by step direction on how to expand the encrypted partition?
