How do you revert or reinstall a configuration file in Debian/Ubuntu?
I accidentally overwrote the file /etc/bluetooth/main.conf. Running dpkg -S /etc/bluetooth/main.conf shows that the package bluez provides it, but when I run sudo apt-get install --reinstall bluez, it doesn't get reinstalled.
Run the following command, replacing package-name with the name of the package:
sudo apt-get -o Dpkg::Options::="--force-confmiss" install --reinstall package-name
If you have .deb package then go to that directory where package is exist and run,
dpkg -i --force-confmiss package-name.deb
You should mv the file out of the way:
mv /etc/bluetooth/main.conf /etc/bluetooth/main.conf.old
apt-get -o DPkg::options::=--force-confmiss --reinstall install bluez
I don't know if you can get apt to overwrite an existing config file, that's why you should move it out of the way first.
