Gradle Error: "Plugin with id 'dev.flutter.flutter-gradle-plugin' not found" - Flutter

 The error message "Plugin with id 'dev.flutter.flutter-gradle-plugin' not found" typically indicates that Gradle is unable to locate the Flutter Gradle plugin. To resolve this issue, you can follow these steps:


1. Make sure your Flutter project is set up correctly and Flutter is installed. You can check this by running `flutter doctor` in your project directory.


2. Verify your `build.gradle` files:


   - Open the `android/build.gradle` file and ensure that the Flutter Gradle plugin is included in the `dependencies` section of the `buildscript` block. It should look something like this:


     ```gradle

     buildscript {

         repositories {

             google()

             jcenter()

         }


         dependencies {

             classpath 'com.android.tools.build:gradle:xxx' // Use the appropriate version

             classpath 'dev.flutter:flutter-gradle-plugin:xxx' // Use the appropriate version

         }

     }

     ```


   - Open the `android/app/build.gradle` file and ensure that the Flutter Gradle plugin is applied in the `dependencies` block. It should look like this:


     ```gradle

     apply plugin: 'com.android.application'

     apply plugin: 'kotlin-android'

     apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle" // Ensure this line is present

     ```


3. If the plugin is missing, you can try to add it manually by editing the `build.gradle` files as described above. Make sure to use the correct version numbers.


4. After making these changes, sync your project with Gradle by clicking "Sync Project with Gradle Files" in Android Studio, or by running `flutter pub get` and then `flutter pub upgrade` in your terminal.


5. Finally, clean and rebuild your project. In Android Studio, you can do this by selecting "Build" -> "Clean Project" and then "Build" -> "Rebuild Project."


If you've followed these steps and still encounter the error, double-check your Gradle files and the Flutter environment setup. You may also want to ensure you're using the correct version of the Flutter Gradle plugin by referring to the official Flutter documentation or the Flutter GitHub repository.

bad character U+002D '-' in my helm template

 In Helm templates, the hyphen character (`-`) can sometimes be treated as a reserved character, particularly when defining values or labels. To include a hyphen character in a Helm template without issues, you can use one of the following approaches: 1. **Quoting the Hyphen:**    You can enclose the hyphen in double quotes, like this:    ```yaml    key: "-"    ```    This way, Helm will interpret the hyphen as a string rather than an operator. 2. **Using Backticks:**    If you need to use the hyphen within a Go template function or inside backticks, you can escape it with a backslash (`\`), like this:    ```yaml    value: `{{ .Values.someField | printf "%s \\-" }}`    ```    The backslash prevents Helm from interpreting the hyphen as a special character. 3. **Variable Assignment:**    Assign the value to a variable and use it. For example:    ```yaml    {{- $hyphen := "-" }}    key: {{ $hyphen }}    ```    This way, you can use the variable `$hyphen` wher

GitLab pipeline stopped working with invalid yaml error

 When your GitLab pipeline has stopped working with an "invalid YAML" error, it means there's a problem with your `.gitlab-ci.yml` file. This could be due to syntax errors, incorrect indentation, or other issues in your pipeline configuration. Here's how to troubleshoot and resolve this issue: 1. **Check for Syntax Errors**:    Carefully review your `.gitlab-ci.yml` file for any syntax errors. Common issues include missing colons, indentation problems, or mismatched quotation marks. Use a YAML linter or an online YAML validator to identify and correct syntax errors. 2. **Indentation**:    YAML relies heavily on proper indentation. Make sure that all lines within the same block have consistent indentation (typically using spaces, not tabs). Incorrect indentation can cause YAML parsing errors. 3. **Dashes and Lists**:    Ensure that you use the correct syntax for lists (arrays) in YAML by starting each item with a dash (`-`). Be consistent with your use of dashes throug

How do I add a printer in OpenSUSE which is being shared by a CUPS print server?

 To add a printer in openSUSE that is being shared by a CUPS print server, you can use the following steps: 1. **Ensure CUPS Client is Installed:**    Make sure your openSUSE system has the CUPS client tools installed. You can install them using the following command:    ```bash    sudo zypper install cups-client    ``` 2. **Discover Available Printers:**    Use the `lpinfo` command to discover available printers on your CUPS print server. Replace `cups-server-hostname` with the hostname or IP address of your CUPS server:    ```bash    lpinfo -v -h cups-server-hostname:631    ```    This command should list the printers shared by the CUPS server. 3. **Add a Printer:**    Use the `lpadmin` command to add a printer. Replace `printer-name` with the name of the printer you want to add and `printer-uri` with the URI obtained from the `lpinfo` command:    ```bash    sudo lpadmin -p printer-name -E -v printer-uri    ```    For example:    ```bash    sudo lpadmin -p MyPrinter -E -v socket://cu
