Isn't RSA better?
Robert's answer was accurate but I'm not sure it was the answer to the question You were asking. Between versions 2.0.9 & 2.0.12 the Default for Key Generation was changed. This change is viewed as minor by many which apparently includes the Ubuntu developers. :) The reason the Default was changed was to make better use of available Hash functions. DSA Signing Keys are limited to 160bit Hashes unless DSA2 is invoked, RSA Signing Keys can utilize all the Hash functions without any 'games' being played. To eliminate any confusion in the future and based upon the number of folks who eventually migrated away from DSA Keys to RSA Keys due to personal perceptions the Default was changed to RSA. Additionally, in the very beginning RSA was encumbered by patents which have now expired. You can easily work around this in Ubuntu at present by selecting option 5 and then generating an RSA Encryption sub-Key.
