Getting a black screen with horizontal colored lines while booting the Tails OS

Question about encountering a black screen with horizontal colored lines while booting Tails OS. This issue can be caused by a variety of factors, including graphics card compatibility, display settings, or hardware-related problems. Here are some general steps to address this issue:


1. **Check Hardware Compatibility**: Ensure that your hardware, including your graphics card, is compatible with Tails OS. Check the Tails website or documentation for information on supported hardware. In some cases, certain graphics cards may not be well-supported.


2. **Try a Different Display Port**: If you're using an external monitor, try different display ports (HDMI, DisplayPort, VGA) to rule out a physical port or cable issue.


3. **Graphics Mode and Resolution**: Tails OS provides options for selecting the graphics mode and resolution during boot. Try different options by pressing the `Tab` key on the boot menu and modifying the boot parameters. Adjusting the resolution might help resolve the issue.


4. **Graphics Card Drivers**: Some graphics cards may require proprietary drivers to function properly. Check if there are any proprietary drivers available for your graphics card and install them if necessary.


5. **Safe Graphics Mode**: Tails OS provides a "Troubleshooting Mode" with a "Safe Graphics Mode." Try booting in Safe Graphics Mode to see if it resolves the issue.


6. **Update Tails OS**: Ensure that you are using the latest version of Tails OS. Newer versions may include bug fixes and improved hardware support.


7. **Create a Bootable USB Again**: If you created the Tails OS bootable USB using a faulty process or corrupted image, recreate the bootable USB using a reliable method and a validated image.


8. **Graphics Compatibility Mode**: Some systems have compatibility modes specifically designed for graphics. You can try enabling compatibility mode or VESA mode in your BIOS/UEFI settings.


9. **Hardware Issues**: If the problem persists, it could be related to hardware problems. Check the health of your RAM, graphics card, and any other components that may be causing display issues.


10. **Ask for Support**: Visit the Tails OS support forum or community to seek assistance from experienced users who may have encountered and resolved similar issues.


11. **Boot Alternative Operating Systems**: To rule out hardware problems, try booting alternative operating systems or Live Linux distributions to see if the issue is specific to Tails OS or if it's more general.


If none of these steps resolve the issue and you continue to experience a black screen with colored lines while booting Tails OS, it's important to seek assistance from the Tails community or consult with a technician who can diagnose and address any potential hardware problems.

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
