This now refuses to upgrade or even install if removed on my 6.11.5 box with the following error:
snmpwalk -v 2c localhost -c public
hrFSMountPoint snmpwalk failure
Couldn't find /boot mount point.
SNMP output: Timeout: No Response from localhost plugin: run failed: /bin/bash
Executing hook script: post_plugin_checks
The /boot mount is there as is the /boot/config/plugins/snmp/ directory.
UPDATE: uninstalling, deleting the directory and trying again still fails with the same error.
Deleting the directory and installing via the HTTPS link doesn't even install but it does create the snmp directory and downloads the packages for install it just never installs them.
UPDATE2: OK, after running 'removepkg net-snmp unraid-snmp' after uninstalling it and deleting the directory I was finally able to install the updated version again from apps. Thanks to kubed for the assist!
