How to fix kernel panic issue on ubuntu 20.4 LTS

 Kernel panic issues on Ubuntu 20.04 LTS can be caused by various factors, such as hardware problems, driver issues, or software conflicts. Here's a general troubleshooting process to help you resolve kernel panic issues:


1. **Reboot Your System:**

   - If your system is currently experiencing a kernel panic, you should start by rebooting it to see if the issue is temporary.


2. **Check for Hardware Issues:**

   - Hardware problems can trigger kernel panics. Run hardware diagnostics or check for overheating, loose connections, or faulty RAM. You can use tools like `memtest` to check your RAM.


3. **Update the Kernel:**

   - Kernel panics can be resolved by updating the Linux kernel to a newer version, which may include bug fixes and improved hardware support. Use the package manager to update your system:

     ```bash

     sudo apt update

     sudo apt upgrade

     ```


4. **Remove Unnecessary or Problematic Kernel Modules:**

   - Some kernel modules can cause problems. Review your loaded modules and try disabling or removing any non-essential ones.


5. **Check for Driver Updates:**

   - Ensure your device drivers are up to date, especially for graphics cards and network interfaces. Outdated or incompatible drivers can trigger kernel panics.


6. **Boot in Recovery Mode:**

   - If your system frequently encounters kernel panics on normal boot, try booting into recovery mode. This mode loads a minimal set of drivers and services, making it easier to diagnose issues.


7. **Examine Logs:**

   - Check system logs for error messages or other information related to the kernel panic. View logs in `/var/log` such as `/var/log/syslog` and `/var/log/dmesg` for clues.


8. **Check Filesystem Integrity:**

   - Filesystem errors can lead to kernel panics. Run a filesystem check using `fsck` to verify and repair your file system. You may need to boot from a Live CD/USB to do this.


9. **Disable Overclocking:**

   - If your system is overclocked, revert to default clock settings to ensure system stability.


10. **Uninstall Problematic Software:**

    - A problematic application or service may be causing the kernel panic. Try uninstalling or disabling software that you recently installed or updated.


11. **Check for Hardware Issues:**

    - Hardware problems, such as failing hard drives or memory modules, can trigger kernel panics. Use hardware diagnostic tools to check for issues.


12. **Hardware Compatibility:**

    - Ensure that your hardware is compatible with Ubuntu 20.04 LTS. Some older or obscure hardware may not be well-supported, leading to stability issues.


13. **Seek Professional Help:**

    - If you're unable to resolve the kernel panic issue or suspect a hardware problem, consider seeking help from a professional or the manufacturer's support.


Remember that kernel panics are often a symptom of an underlying issue, and diagnosing and fixing the root cause can require careful investigation. Keep detailed records of error messages and changes you make, and consider reaching out to the Ubuntu community or support forums for additional assistance.

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
