I want to upgrade my Ubuntu 13.04 to the latest Ubuntu 13.10, but it seems it doesn´t want to do it so. This is what I´ve tried (after a backup):
1. Using the GUI first:
Clicked on "Software Updater"
It appears the message "Software Updates are no longer provided for Ubuntu 13.04. To star secure, you should upgrade to Ubuntu 13.10".
I click on "Upgrade..." Button
After the "authentication is required" message...
Nothing happens! I wait and wait and nothing happens. No process, no nothing.
2. I try then the command line method typing these:
sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade
After all processes are finished, I then type:
sudo apt-get install update-manager-core
The message I receive is:
update-manager-core is already the newest version.
I then type:
sudo apt-get autoremove
It does remove some gimp related help file.
And then I type:
The messages I get are these:
Checking for a new Ubuntu release. No new release found
Then I go again to the GUI Software Updater, and in fact, I still got the 13.04 version.
The same thing after a system restart.
What should I do?
