Upgrading Ubuntu 9.04 to 9.10 when Update Manager doesn't let you
- by nickf
I've been trying to upgrade my installation of Ubuntu 9.04 to 9.10, but all of the instructions I've found haven't been helping. They mostly say to run the update manager and it'll tell you that there's a new distribution ready. Well, mine doesn't say that.
Things I've run or checked:
update-manager -d says:
Your system is up-to-date
The package information was last updated less than one hour ago.
I've set it to get all new distributions, not just LTS
$ cat /etc/update-manager/release-upgrades
[DEFAULT]
# default prompting behavior, valid options:
# never - never prompt for a new distribution version
# normal - prompt if a new version of the distribution is available
# lts - prompt only if a LTS version of the distribution is available
Prompt=normal
I'm definitely running 9.04
$ lsb_release -r
Distributor ID: Ubuntu
Description: Ubuntu 9.04
Release: 9.04
Codename: jaunty
Even running the release upgrade from console doesn't help:
$ sudo do-release-upgrade
Checking for a new ubuntu release
No new release found
This is running from behind a proxy, but I've set it up such that the regular upgrades and apt-get etc doesn't complain. (export http_proxy=http://myuser:mypass@myserver:8080/)
Could you think of anything else which might be stopping me from upgrading?
