package apt 1.0.1ubuntu2 failed to install/upgrade: package apt is already installed and configured

[Dmikam]

Upgrading from Gnome-Ubuntu 13.10 to 14.04, in some moment it froze, so after waiting a while (with no activity in any tty and in htop) I rebooted. Afrer reboot I entered into Recovery mode (the normal one didn't boot) and selected Fix packages dependencies (os something like that). After it was terminated I'v been able to boot but there was some error report messages including this one.
