Environment

Aria Operations for Networks 6.14

Cause

Underlying OS ubuntu22 library file  is missing which is required dependency for chrome which seems to be removed recently and needs to be installed explicitly

Resolution

To workaround this issue execute the below steps to explicitly add the missing library file to the Aria Operations for Networks version 6.14 appliances. 

Note:

Library file is attached to this KB under attachment section.
This library file needs to be moved to all the platform and collector nodes in the deployment.

Steps as below:

1. Download the library file attached (see attachment section)  and save it to a local system.
   
   File name: libnss3_with_deps.tar
   
   
2. WinSCP the library file  to all the Platform and collector nodes in the deployment under location:
   
   

   /home/support

   
   
   
3. Take a SSH/putty session on the Aria Operations for Networks appliances and login with username support
   
   
4. Validate that file is under location /home/support using command
   
   

   support@platform1:~$ ls -lrth
   total 1.5M
   -rw-r----- 1 support support 1.5M Jan 17 18:17 libnss3_with_deps.tar
   

5. Execute below commands one by one:
   
   

   tar -xvf libnss3_with_deps.tar
   sudo dpkg -i var/cache/apt/archives/libnspr4_4.35-0ubuntu0.22.04.1_amd64.deb
   sudo dpkg -i var/cache/apt/archives/libnss3_3.98-0ubuntu0.22.04.2_amd64.deb
   sudo dpkg -l | grep libnss3 where output shows libnss3 installed
   
   

6. Verify PDF Export functionality.
   
   
7. PDF Export should work as expected when clicked on Export button on the GUI.
