Hello!

I have a problem with upgrading from ubuntu 7.10 to ubuntu 8.04 LTS.

i receive the following errors:

when trying do-release-upgrade:



[root@computer] # do-release-upgrade
Checking for a new ubuntu release
Done Upgrade tool signature
Done Upgrade tool
Done downloading
extracting '/tmp/tmpX-h3q_/hardy.tar.gz'
authenticate '/tmp/tmpX-h3q_/hardy.tar.gz' against '/tmp/tmpX-h3q_/hardy.tar.gz.gpg'
exception from gpg: GnuPG exited non-zero, with code 131072
Debug information:

gpg: WARNUNG: Unsichere Zugriffsrechte des Home-Verzeichnis `/tmp/tmpX-h3q_'

gpg: Signatur am Fre 09 Mai 2008 18:46:50 CEST mit DSA Schlüssel, ID 437D05B5, erfolgt
gpg: Unterschrift kann nicht geprüft werden: Öffentlicher Schlüssel nicht gefunden

Authentication failed
Authenticating the upgrade failed. There may be a problem with the network or with the server.


and when I try apt-get dist-upgrade:



[root@computer] # apt-get dist-upgrade
Paketlisten werden gelesen... Fertig
Abhängigkeitsbaum wird aufgebaut
Reading state information... Fertig
Berechne Upgrade...Fertig
0 aktualisiert, 0 neu installiert, 0 zu entfernen und 0 nicht aktualisiert.


also, when i try upgrading via update-manager (the GUI), it tells me that a new version 8.04 LTS is available.
when i try to update, i get the following output on the console:


[root@computer] # update-manager
extracting '/tmp/tmpc1475D/hardy.tar.gz'
authenticate '/tmp/tmpc1475D/hardy.tar.gz' against '/tmp/tmpc1475D/hardy.tar.gz.gpg'
exception from gpg: GnuPG exited non-zero, with code 131072
Debug information:

gpg: WARNUNG: Unsichere Zugriffsrechte des Home-Verzeichnis `/tmp/tmpc1475D'

gpg: Signatur am Fre 09 Mai 2008 18:46:50 CEST mit DSA Schlüssel, ID 437D05B5, erfolgt
gpg: Unterschrift kann nicht geprüft werden: Öffentlicher Schlüssel nicht gefunden


this translates pretty much to:
gpg:Warning: Insecure access rights of the home directory '/tmp/tmpc1475D'

and
gpg: signature cannot be checked: public key not found

the GUI Application shows the following error:



Echtheitsbestätigung fehlgeschlagen
Die Aktualisierungen konnten nicht auf ihre Echtheit überprüft werden. Möglicherweise gibt es Probleme mit dem Netzwerk oder dem Server

In english, this translates to the following:

Authenticity check failed
The Updates could not be checked for authenticity. Maybe there are Problems with the Network or the Server.


I don't understand why apt-get thinks that there is no distribution upgrade available!


Does anyone have any idea how this can be resolved?

here is the content of my /etc/apt/sources.list:
