@bloodynacho Welcome to the Rockstor community.
These emails are from the underlying CentOS system and don’t actually indicate that the packages are being updated, just that they are being downloaded ready. When Rockstor’s email notifications are enabled you receive all email that is directed towards the root (main system) user and this is just one of them. The default appears to be to auto download but unless you have selected to also install they are just downloaded. With auto update enabled you would also receive email indicating what was actually updated and from what prior version.
Also note that you can update everything except the Rockstor package by clicking on the flashing icon to the left of the kernel version displayed in the top right of the interface:
Though we don’t yet provide an indicator of the ‘in progress’ update once it’s initiated so do leave the box for a while before turning off or rebooting to help avoid potential issues with incomplete updates.
This way you can at least keep the rest of the system updated on a manual basis.
Hope that helps to clear this up. It’s essentially noise and normal in this setting.
