Solution:

1. The info folder is now renamed

sudo mv /var/lib/dpkg/info /var/lib/dpkg/info.bk

2. Create a new info folder

sudo mkdir /var/lib/dpkg/info

3. Installation and repair

sudo apt-get update
sudo apt-get install -f

4. After performing the previous step, some files are generated in the info folder. Now move all these files to the info.bk folder

sudo mv /var/lib/dpkg/info/* /var/lib/dpkg/info.bk

5. Delete your new info folder

sudo rm -rf /var/lib/dpkg/info

6. Restore the original info folder and modify the name

sudo mv /var/lib/dpkg/info.bk /var/lib/dpkg/info
