Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following packages have unmet dependencies:
libcurl4-openssl-dev : Depends: libcurl3 (= 7.21.3-1ubuntu1) but 7.21.3-1ubuntu1.5 is to be installed
Depends: libkrb5-dev but it is not going to be installed or
hurd but it is not installable

sudo apt-get update
没有帮助。
deb http://security.ubuntu.com/ubuntu maverick-security main universe restricted multiverse
在 Synaptic Package Manager 中，然后 sudo apt-get update 也没有帮助。
