Steps to reproduce

  1. I don’t know!

Expected behaviour

  • dietpi-banner should display

DietPi vX.X.X : Update available

and

dietpi-update : Run now to update DietPi from vX.X.X to vY.Y.Y

when an update is available

Actual behaviour

  • dietpi-banner does not display the update lines

Extra details

  • it seems to me this is a low-priority but recurring issue. Usually around Christmas, I notice the device has not been updated for a long time. I then run dietpi-update and it works for months before eventually stopping displaying the update lines again
  • nowadays, the device is usually not connected to the internet when turned on (the internet box takes way longer to boot than the Pi4)
  • even when it is connected to the internet at boot (like on occasional reboots), the update lines are missing
  • manually running dietpi-banner and just validating has made the update lines appear one time, but they stopped appearing before I updated the system
  • I installed some software with apt today and now the update lines are displayed
  • I’m not expecting a fix but merely guidance as to what to check and report in the future, if the bug reproduce, with this bug report for reference

This an explicit update check enable the banner notification?
