I deleted the dpkg binary file using sudo rm /usr/bin/dpkg now I am encountering problems you can assume what kind. Later I found out that it was a very impotent file. I am a new ubuntu user in the learning stage. I did not know what I was doing. I refered to this Accidentally deleted /usr/bin/dpkg post but when I tried the solution I get
Could not exec dpkg!
E: Sub-process /usr/bin/dpkg returned an error code (100)
I was able to fix this when I changed the file permissions
sudo chmod a+x /usr/bin/dpkg
Now when running
sudo apt-get install --reinstall dpkg
I get a number of errors including
`File "/usr/lib/update-notifier/package-data-downloader", line 29, in <module>
import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'
