When I installed Ubuntu, I opted to encrypt the whole OS. I enter a password every time my computer boots up (note: I'm not talking about the log-in screen -- I enter a password to get to that screen). I'm not trying to remove this or anything, but I want to change the password. Someone recommended that I check out the Gnome Disk Utility, which I did. I can see my computer's hard drive, but, when I click on it, I'm only able to do anything related to encryption on one of the partitions. I assumed this was the partition that I needed to change the password to, but, after I edited the password, I had to use the previous password upon the next boot. I have no idea what I edited now (I removed the password from it because I have no clue what it is), and I still have no clue how to change the password that I want to change. Hoping someone can help.
