Okay, in that case you do have a problem. The update sure is going to be pretty large... How I'd go at it, (but of course anyone is free to do whatever they please)I'd first balance my btrfs and make sure there's really lots of free space available Then I'd switch to 1.1.1.27 on console, and update with zypper; "ssu re 1.1.1.27; ssu ur; zypper ref; zypper up" If "zypper up" still says something like ~260MB of updates, then I'd contact Jolla Care, and not start update.
