@zhangjl I'm not sure how to fix that problem, if you're wanting to restore your package lists to how they were you can always revert them by copying them back
sudo cp ~/sources.list /etc/apt/sources.listbut I don't think that'd fix the package signatures. If it were me, since it looks like it's only two packages, I'd just re-install them after the install was successful.
