I am trying to upgrade from 13.04 to 13.10 following the instructions given in https://help.ubuntu.com/community/SaucyUpgrades:
1)
sudo apt-get install update-manager-core
Output:
Reading package lists... Done
Building dependency tree
Reading state information... Done
update-manager-core is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
2)
do-release-upgrade
Output:
Checking for a new Ubuntu release
No new release found
Many people have similar problems with upgrades for other versions. The most mentioned solutions I found are 1) to change from Prompt=lts to Prompt=Normal in /etc/update-manager/release-upgrades and 2) to do the release upgrade as a normal user instead of root user. Non of these worked for me.
Any idea to solve my problem?
Thank you.
