How do I completely remove and reinstall Samba on Debian?
sudo apt-get purge samba
will remove the entire package, along with configuration files, which apt-get remove samba won't. After the purge, reinstall samba using
sudo apt-get install samba
from man apt-get:
purge
purge is identical to remove except that packages are removed and
purged (any configuration files are deleted too).
On Ubuntu (17) I did
apt purge samba samba-common
followed by
apt install system-config-samba
which worked for me.
