Hi,
I can't find in the logs what went wrong on the first install, but usually those issues can be resolved with:

sudo apt-get install --reinstall libsnmp30

A bit harder (can break your system more than it is, so be careful) :
sudo dpkg --force-remove-reinstreq --remove <package_name here>
sudo apt-get update
