Hi Ubuntu Mate community !!! i am having issues when i type my security key to encrypt my hard disk,i get this error message : error message: “cryptsetup: cryptsetup failed, bad password or options?”. i do type and re-type my security key correctly ( iguess so )with Uppercase letters,lowercase letters,numbers and symbols from the keyboard & space but doesn’t works (the system says it’s a strong password) then i do change it to normal characters (no lower case,uppercase,etc) doesn’t works neither …any suggestion please ??? i am new to this OS,i did find this online but really dont now what really is a passphrase … http://www.dsm.fordham.edu/cgi-bin/man-cgi.pl?topic=cryptsetup
Hi @Sexybaldguy,
I would follow the advice here:
https://help.ubuntu.com/community/FullDiskEncryptionHowto
https://help.ubuntu.com/community/EncryptedHome
I cannot really help you much further as I don’t use any encryption of any sort!. 
Hi @wolfman,i never take my PC out of home,but to be honest i am a paranoid about privacy & security,are like my second name 
without that features,i feel i am not complete …
Thanks for your reply but those articles doesn’t help much as i told you before i am new with this Ubuntu OS;i did use windows for several years but feeling tired of it and i really like this Ubuntu operating system,just hope to get more replies to make the encryption feature works perfectly.
I think i will buy next time Ubuntu privacy remix or one of those OS for paranoids as me
