This method include removing all files related to the corrupted file. Don’t worry you can download them again and it won’t affect your existing files and applications.

First you need to see all the files that are causing this problem. For that just ls /var/lib/dpkg/info You might have got lot of files we just need corrupted file in our case it is bacula-console-qt so we’ll use grep to filter the files.

sudo ls -l /var/lib/dpkg/info | grep -i bacula-console-qt
