add bridge failed: Package not installed Linux Bridge Not working Ubuntu Mint Debian solution
If you get this error in your logs:
add bridge failed: Package not installedThis error normally means one of two things.
1.) Is your brctl (bridge-utils) installed?
On Mint/Debian check for "brctl". If it's not there do
sudo apt install bridge-utils uml-utilities
2.) Is your bridge.ko (bridge kernel module loaded?).
On some installs I have seen that you cannot modprobe bridge.ko (it fails) because your list of dependencies is broken for some reason.
Do this to restore a list of modules:
sudo depmod
Then try to modprobe bridge again
modprobe bridge
3.) If the bridge.ko is missing make sure you install the package for your kernel that contains the modules
eg: linux-modules-extra-generic linux-modules
After fixing everything, this should now work:
brctl addbr br0
