Here the c++ code of apt

    // See if we need to abort with a dirty journal
    if (CheckUpdates() == true)
    {
       close(d->LockFD);
       d->LockFD = -1;
       const char *cmd;
       if (getenv(\"SUDO_USER\") != NULL)
          cmd = \"sudo dpkg --configure -a\";
       else
          cmd = \"dpkg --configure -a\";
       // TRANSLATORS: the %s contains the recovery command, usually
       //              dpkg --configure -a
       return _error->Error(_(\"dpkg was interrupted, you must manually \"
                              \"run '%s' to correct the problem. \"), cmd);
    }

so there is a dirty journal. (maybe due to a power off during the chroot update)
