Not quite, there are multiple upgrade paths "to 2056", which depends on which build one currently has. There always is a "full" upgrade type - download complete rev2056 and flash all of it. There are also "delta" upgrade paths e.g. "2055 -> 2056", "2054 -> 2056", "2053 -> 2054", which means: * if you are on 2053 - two delta updates will be applied, one to upgrade to 2054 and another one to upgrade to 2056 * if you are on 2054 or 2055 - one delta update will be applied to upgrade straight to 2056 If you look at the real upgrade manifest (e.g. https://system-image.ubuntu.com/devel-proposed/mako/index.json ) you can see that there is { "type": "full" } for each revision, but also one or more { "base": XXX , "type": "delta" } updates for each { "version": YYY }. -- Regards, Dimitri. -- Mailing list: https://launchpad.net/~ubuntu-phone Post to : ubuntu-phone@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-phone More help : https://help.launchpad.net/ListHelp
