A recent Linux system update caused some DNS issues affecting HOOBS Box users running on model HSLF-1 as well as DIY installs on Raspberry Pi boards.
If you are not able to install plugins or your plugins fail to connect to the internet after a System update, and your logs read “Plugin site unavailable”,
this likely affects you. To fix the issue, you need to remove the resolv.conf file and reboot your system using the following terminal command:

sudo rm /etc/resolv.conf; sudo reboot

Input your terminal password at the prompt and press enter. Your password will not show as you type it in the terminal.
