This question already has an answer here:
I have to upgrade an Ubuntu 12.04 to the last stable Ubuntu 13.10 but I have some doubts about how do it:
1) The first doubt is related to the fact that reading online seems that is not a smart thing update directly from 12.04 to 13.10 but I read that is better do it by steps:
from 12.04 to 12.10, then from 12.10 to 13.04 and finally from 13.04 to 13.10
Is it true?
2) Trying to perform the previous operation (the update from 12.04 to 12.10) following this official tutorial: https://help.ubuntu.com/community/QuantalUpgrades
I have followed the previous tutorial and I have activate the notification "For any new version" of the system but in the Update manager appear to me a strange thing, infact it say to me that is available the new 14.04 release
Reading online I see that 14.04 will be the new LTS and that this will be available in April of 2014, so what is this? is it a beta version or something like this?
I can't chose to upgrade to 12.10 or 13.10.
What can I do to upgrade my system to the last stable version?
