If my understanding is correct the solutions snap should be used to read and write configuration files. I'm trying to do this in Go, and have added the "active-solution" plug to my snapcraft.yml plugs: active-solution: interface: content content: solutions target: $SNAP_COMMON/solutions My code is checking if the directory and file exists, and creates them if not. Creating seems to work, but reading the file results in the following error: Could not read configuration file: open /var/snap/rexroth-solutions/common/solutions/DefaultSolution/configurations/Default/my-snap/config.json: permission denied Trying to view the created directory from the sidebar in the Configurations menu of the virtual control shows this error: open /var/snap/rexroth-solutions/common/solutions/DefaultSolution/configurations/Default/my-snap: permission denied This is the Go source code, any ideas what permissions need to be changed when creating the configuration directory and file? type Config struct { Greeting string `json:"greeting"` } snapCommon := os.Getenv("SNAP_COMMON") activeConfiguration := path.Join(snapCommon, "/solutions/activeConfiguration") resolvedPath, err := os.Readlink(activeConfiguration) if err != nil { log.Fatalln("Could not resolve active configuration path: ", err) } configurationPath := path.Join(resolvedPath, "/my-snap") if _, err := os.Stat(configurationPath); os.IsNotExist(err) { os.Mkdir(configurationPath, os.ModeDir) } configurationFile := path.Join(configurationPath, "/config.json") if _, err := os.Stat(configurationFile); os.IsNotExist(err) { file, err := json.MarshalIndent(Config{Greeting: "Hello World"}, "", " ") if err != nil { log.Fatalln("Could not write default configuration file: ", err) } ioutil.WriteFile(configurationFile, file, 0644) } config := Config{} file, err := ioutil.ReadFile(configurationFile) if err != nil { log.Fatalln("Could not read configuration file: ", err) } err = json.Unmarshal([]byte(file), &config) if err != nil { log.Fatalln("Could not parse configuration file: ", err) }   ...
