[SOLVED] cryptsetup - how to open luks drive

I see this issue:  https://bbs.archlinux.org/viewtopic.php?id=264274

i seem to have a similar issue, but i don't know how to resolve. 

I am using LUKS 1
I updated to 5.11 yesterday
I have a usb with 4.17.3 and i still cannot unlock my luks drive. 
I cannot figure out how to unlock the drive if it won't accept my key.

Re: [SOLVED] cryptsetup - how to open luks drive

what if you use foobar (some crypt mapping name a-z) instead of /mnt (never seen that with cryptsetup before)
