See my screen output log. "do-release-upgrade" command not working and python-apt is NOT installed and there are NO broken dependecies in system:
root@router:/etc/dhcp# LANG=C apt-get check Reading package lists... Done Building dependency tree Reading state information... Done So, there are missed dependencies. In other way I will not able to delete python-apt because of depend3ncy problems. So, if I can delete this package without broken dependencies, then no dependency is working. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1178245 Title: missed python-apt dependency To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1178245/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
