This corruption mainly occurs due to some unnecessary interruption while installing the package.

So, we used the below command to reconfigure and repair it.

sudo dpkg ––configure –a


2. Using force install method

So, if the package installation fails, we use the below command

sudo apt-get install –f

The -f option indicates fix-broken. It repairs broken dependencies that occur when download interruption happens.


3. Removing the troublesome packages and post info files

Also, we can fix this error by removing the error causing software packages.

sudo apt remove package_name

Similarly, if we know the error causing package, then the installation files will be in the /var/lib/dpkg/info file.
