How to find and sign nvidia driver?

 To find and sign NVIDIA drivers on Linux, especially if you're dealing with secure boot or driver verification requirements, you'll need to obtain the NVIDIA driver package, sign it with a trusted Secure Boot key, and load it into the Secure Boot database. Here's a high-level overview of the process:


1. **Download NVIDIA Drivers:**

   - Visit the official NVIDIA website to download the Linux drivers for your GPU. Make sure to download the correct driver version for your hardware.


2. **Prepare Your System:**

   - Ensure that your system is set up for Secure Boot, if required. Secure Boot is often used to verify the integrity of kernel modules and drivers, especially on UEFI systems.


3. **Generate a Key Pair (Optional):**

   - If you need to sign the driver for Secure Boot, you may need to generate a key pair. The process can vary depending on your distribution. You can use the `openssl` command to generate a key pair. For example:


     ```bash

     openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -days 36500 -subj "/CN=Your_Key_Name/"

     ```


4. **Sign the Driver:**

   - Use the `nvidia-installer` tool to install the NVIDIA driver. During installation, you will have the option to sign the NVIDIA kernel module with your generated key. Here's an example:


     ```bash

     sudo NVIDIA-Linux-x86_64-<version>.run --module-signing-secret=<path_to_MOK.priv> --module-signing-public-key=<path_to_MOK.der>

     ```


5. **Add the Key to Secure Boot (MOK - Machine Owner Key):**

   - If you generated a key pair and signed the driver, you'll need to enroll the MOK in your system's Secure Boot firmware. Reboot your system, and during the boot process, you will be prompted to enroll the key. Follow the on-screen instructions.


6. **Load the NVIDIA Driver:**

   - After enrolling the key, your signed NVIDIA driver should load correctly.


This process allows you to install and sign the NVIDIA driver on systems with Secure Boot. Keep in mind that the exact steps may vary depending on your Linux distribution and the version of NVIDIA drivers you are using. Always refer to the official documentation provided by your distribution and NVIDIA for the most accurate and up-to-date instructions.

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
