Dependency missing, check validate

Help
1

I have updated LibreNMS (git pull, ./daily.sh, and ./validate.sh all on the librenms user account), and since the upgrade I am seeing a notification on the WebGUI stating " dependency missing, check validate ". I did notice that some items were not installed, which the ./validate.sh output asked me to install using the following commands:

./scripts/composer_wrapper.php install --no-dev
composer install --no-dev

Since then, validate.sh is showing up perfectly on the CLI but the WebGUI is still showing that popup.
Unfortunately I did not save the command output for you guys to see. Everything does appear to be working fine and it seems as if that notification is cosmetic (I don’t think I have lost any functionality on LibreNMS).

Not sure how to proceed from here. What do I do to either remove the notification or resolve the dependencies that is not being displayed on ./validate.sh output?

$ ./daily.sh 
Updating SQL-Schema                                OK
Cleaning up DB                                     OK

Check if you have mbstring installed:

presumably when you ran this command, it gave no errors or indication of missing dependencies ?

./scripts/composer_wrapper.php install --no-dev
composer install --no-dev

Try log off LibreNMS and re-authenticate and see if you still get the message.

Presumably you don’t have SeLinux installed ? run sestatus command. ( Error: Missing dependencies! - Librenms)
