Looks like you upgrade the DB as well. You need to confirm librenms can talk to the DB. correct username and password in config.php

i’m using the default

Database config

$config[‘db_host’] = ‘localhost’;
$config[‘db_user’] = ‘librenms’;
$config[‘db_pass’] = ‘D42nf23rewD’;
$config[‘db_name’] = ‘librenms’;

Today i re-deployed VM, configured fine then started the daily upgrade.
Now i’m again in the same condition.

I’m also having the same issues. Both before and after apt update && apt dist-upgrade

This started off with issues connecting to the UI, with a HTTP ERROR 500 and log messages

in addition to the Undefined index: name messages listed in previous posts.

Workaround for now:
This worked for me while I await the real answer.

I confirm that workaround works!

Try this, it is worked for me, in following file:

vendor/laravel/framework/src/Illuminate/Foundation/PackageManifest.php

Find this line and comment it

$packages = json_decode($this->files->get($path), true);

Add two new lines after above commented line

$installed = json_decode($this->files->get($path), true);
$packages = $installed['packages'] ?? $installed;

Thanks
