解决办法：
sudo cp /var/lib/dpkg/status status.bkp
sudo gedit /var/lib/dpkg/status
Search for the package name that appears in the error. Note that, in our case the culprit package was ‘urd’ which was in ‘purge reinstreq half-installed’ state. After you have located the culprit package, delete the section of information related to that package and save the file. In our case, we deleted the section related to ‘urd’ inside the rectangle and saved the file. Close ‘gedit’ when done.
