After upgraded my Ubuntu to 17.04, the package system is broken. When I execute any of the following commands, I got some error.

sudo apt-get full-upgrade
$ sudo apt-get full-upgrade Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt --fix-broken install' to correct these. The following packages have unmet dependencies: click-apparmor : Depends: python3-apparmor-click (= 0.3.17) but 0.3.18 is installed E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
I also have tried the following solutions but they did not work.
Anyone know how to fix it without reinstalling Ubuntu?
