I have a experienced a slightly odd behaviuour in the Ubuntu upgrade utility and am lefting wanting to know. Also I am trying to replicate an environment as closely as possible, and upgrading from 12.10 to 13.04 may be relevant.
I downloaded 12.10.4 server, installed it as close to "defaults" as possible, and ran do-release-upgrade
— this bumped me straight up to 13.10, without first trying to move me to 13.04
How do I define a specific release for this process? (id est, where are the configs for do-release-upgrade)
I've only found this post to be vaguely relevant but does not answer my question…
Best Answer
the file is in /etc/update-manager/release-upgrades
i assume this happens because 13.04 is already end-of-life and therefor the next supported version is 13.10 though not 100% sure, see wikipedia
change
or try
after the config change.
This seems to be the official solution to upgrade from 12.10 to 13.04
