Yes. I am using 32 Bit version of Ubuntu.
Then, can I continue using the 0.9.2.3?
How can export armory's wallet to another computer with a 64 bit version and then install the 0.93 version?
Thank you very much for your help.
You should stick to 0.92.3 if you intent to use a x86 OS to get Armory online with.
To export wallets you have to use the Backup tool with each of your wallets. Go to the Properties dialog of each one of your wallet and pick "Backup This Wallet" (or "Export Watching-only Data" if it's a WO) from the left side menu.
Then use the import tool on your other instance of Armory (top left corner button on the main lobby)
