I just clean-installed Ubuntu (12.04.4 lts) for my first time about a week ago and have been having problems with swap from the get-go. Initially, I was receiving the error message "The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present" during boot. In Gparted, I could see my hard drive as well as a bunch of empty space that was supposed to be my swap. After mucking about on the internet and such, I tried the answer to this person's question, which is really just a summary of this post.
I went through the steps and had to re-do them a bit because there were some missing steps in the comments, but I at least got the error message to go away (hooray) although I still face the problem in the title. At every boot I need to "swapon" the swap partition in Gparted (I'm sure there's another way, but it's all I know for now). What do?
I'll post the outputs of any commands you want as long as you show me how to paste the results here properly :D
