Comment 5 for bug 615943

Thank you for the quick response. Eucalyptus-common *is* installed, at the correct version... I wonder if you previously installed eucalyptus, then partially uninstalled.

This might be the reason for the error:

/var/lib/dpkg/info/eucalyptus-nc.postinst: 47: cannot create /etc/eucalyptus/eucalyptus-nc.conf: Directory nonexistent

Meaning '/etc/eucalyptus' does not exist -- like it was forcefully removed ('rm -rf /etc/eucalyptus'-type of action).

Can you please reinstall -common:

sudo apt-get --reinstall install eucalyptus-common
