Ich verwende Ubuntu 11.04. Der Update-Manager hat einmal die neue Version „oneiric“ gefunden und zeigt immer noch diesen Bildschirm, wenn ich mich mit ssh anmelde:
Welcome to Ubuntu 11.04 (GNU/Linux 2.6.38-14-generic x86_64)
* Documentation: https://help.ubuntu.com/
0 packages can be updated.
0 updates are security updates.
New release 'oneiric' available.
Run 'do-release-upgrade' to upgrade to it.

Aber ich habe damals kein Upgrade durchgeführt und meine apt-Quellen geändert. Und jetzt kann ich nicht auf „oneiric“ upgraden. do-relase-upgrade zeigt:
$ sudo do-release-upgrade
Checking for a new ubuntu release
No new release found
$
Und apt-get dist-upgrade zeigt:
$ sudo apt-get dist-upgrade

So aktualisieren Sie von Ubuntu 11.10 oder Ubuntu 10.04 LTS auf einem Server oder System:Installieren Sie update-manager-core Paket, falls es noch nicht installiert ist; Starten Sie das Upgrade-Tool mit dem Befehl sudo do-release-upgrade -d; und befolgen Sie die Anweisungen auf dem Bildschirm. Beachten Sie, dass das Server-Upgrade jetzt robuster ist und den GNU-Bildschirm verwendet und automatisch neu verbunden wird, wenn z. Verbindungsprobleme.
