ISSUE
I can't start debugging, I've tried different things, but it keeps telling me "Unable to start debugging. Launch options string provided by the project is invalid. Unable to determine path to debugger. Please specify the "MIDebuggerPath" option.

I've tried setting MIDebuggerPath to /usr/bin/ or usr/share and some other paths, but no luck.

My launch.json looks like this:
{
"version": "0.2.0",
"configurations": [
{
"name": "(gdb) Launch",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}/04_printf/printf",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": true,
"MIMode": "gdb",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
]
},

]
}

Please, help me, I've already wasted 2 hours trying everything I could.
