Hi,

have you installed the required packages first?

Hi!
Yes.
This is the last guide I followed.
https://docs.librenms.org/Installation/Installation-Ubuntu-1804-Apache/

seems unzip is not installed

[Monitoring Instances with LibreNMS on Ubuntu Focal Fossa]
It starts with the follow issue.
The error is
Package jakub-onderka/php-console-color is abandoned, you should avoid using it. Use php-parallel-lint/php-console-color instead.
Package jakub-onderka/php-console-highlighter is abandoned, you should avoid using it. Use php-parallel-lint/php-console-highlighter instead.
Package spatie/laravel-cors is abandoned, you should avoid using it. Use laravel/framework instead.

I looked for these requirements.txt and run pip3 install for any package mentioned but still the same error.

Dude, I’ve readed your post just when I woke up this morning, and was very soon :slight_smile:

Your install is already done.

Those are just a few warnings (that will be fixed at some time) but your installation is done and should be almost ready to start working.

yes I am in. Thanks. Its working. Time to explorer how can I make interface traffic graph which I had issue with Cacti as it was not showing the correct values.
