Issue description 

Possible causes 

1. The broken CAPTCHA image issue is often the result of either a browser cache problem or missing fonts required for rendering the CAPTCHA. Since Linux distributions typically do not include Microsoft fonts by default, you may need to install them manually.
   

Prerequisites 

1. Access to the EventLog Analyzer user interface.
2. Access to the Linux server on which EventLog Analyzer is installed with root or similar permission to install a package.
   

Steps to follow 

1. sudo apt install fontconfig  
   

1. This command installs Fontconfig, a library and command-line utility used by Linux systems to manage and configure fonts. It enables font discovery, font substitution, and automatic fallback for missing fonts.
   

1. sudo apt install ttf-mscorefonts-installer  

1. This installs a set of Microsoft TrueType core fonts, such as:

• Arial
• Verdana

1. sudo fc-cache -f  
   
1. This command forces a refresh of the font cache used by Fontconfig.

• -f indicates "force" the rebuild, even if no changes are detected.
• This ensures that any newly installed fonts (like the Microsoft fonts) are detected and available to applications.
  

Tips 

1. To verify if the fonts have been successfully installed, run the below command 
   fc-match Arial
2. This tries to find a font on your system that matches Arial. If the exact font isn't available, it returns the closest fallback (e.g., Liberation Sans, DejaVu Sans, etc.).
   fc-match Verdana
3. This is same as the above command, which checks for Verdana.
