It *might* work with 12.04/12.10 but only the 32-bit versions. Please let me know if you try this. I have been meaning to make a 64-bit version, and/or 12.04/12.10, but I hate adding more things to support (luckily, that's not part of the regular release schedule, only occasionally remake the offline bundle since offline version isn't so important).
Okay I will let you know if I will try it. I have one more question regarding to offline wallet: Armory and your site tells me to make a paper backup of my wallet but I guess a digital copy does the job too or can the backup only be restored with a paper wallet? Maybe a stupid question but I want to get sure.
Thank you!
Either one will work, though you will need your encryption password for your digital backup. The reason I recommend paper is because if the paper is intact, it's guaranteed to be useful 10-20 years from now when you need it (even if it's thoroughly faded, you'll still be able to recover it). Making only one digital backup is like betting your life-savings that a $3 USB key sitting in box somewhere will still work 20 years from now. I wouldn't make that bet

Okay I understand your intention
Two more question

->
- When my armory wallet is encrypted, is the paper wallet encrypted too?
- Do I have to worry that the wallet format of the paper wallet is no more supported in x years !?
I really love your client and hope you won't stop the development someday!
