hi all, an update to recent test deployment of jarischaefer’s LibreNMS image,  
**its broken** on both **Synology and general Debian** installs

## Do NOT update to latest image

Do NOT update to latest image if you doing maintenance of your containers

Tested on:  
Syno 916+  
DSM 6.2.3-25426

| **Version** | [1.65.1 - Sat Jul 11 2020 03:56:16 GMT+0800](http://www.librenms.org/changelog.html) |
| --- | --- |
| **Database Schema** | 2020\_06\_23\_00522\_alter\_availability\_perc\_column (170) |
| **Web Server** | nginx/1.15.8 |
| **PHP** | 7.4.7 |
| **Python** | 3.6.9 |
| **MySQL** | 10.4.12-MariaDB-1:10.4.12+maria~bionic |
| [**Laravel**](https://laravel.com/) | 6.18.20 |
| [**RRDtool**](https://oss.oetiker.ch/rrdtool/) | 1.7.0 |

## Discovery works but never polls after

## Test with Ubuntu VM

```auto
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.4 LTS
Release:	18.04
Codename:	bionic

```

Thought I’d test this image in a VM to cancel out some Syno permission problems to make sure the image is working

### poller-wrapper.py error

### Latest working version: 1.63

If anyone tested with the latest version and works, would appreciate if they could report with any work arounds/solutions 🙂

For new users deploying a fresh install, I’ve tested from latest, v1.65, v.1.64, with poller-wrappy.py errors, please use v1.63

```auto
Version 1.63 - Tue Apr 28 2020 11:52:42 GMT+0800
Database Schema 2020_04_19_010532_eventlog_sensor_reference_cleanup (164)
Web Server nginx/1.15.8
PHP 7.4.5
MySQL 10.5.4-MariaDB-1:10.5.4+maria~focal
RRDtool 1.7.0

```

Eg:  
`docker pull jarischaefer/docker-librenms:1.63`

Meanwhile I’ll go report to jarischaefer 😅
