Afterwards I had an error with the update-manager and cancelled then the upgrade.
I guess my errors were caused by myself: I installed updates from 8.04 including a new kernel if I remember correctly. Afterwards I did not reboot, but changed the setting to be able to install non-LTS-distribution-upgrades and then started the upgrade to 8.10.
I could repair the system by doing a "dpkg --configure -a".
Now my system is consistent again and works. Only the passwords for wireless-security and my fingerprint seem to be lost and I had to re-enter them.
