We have now had 3 instances where after doing a Host OS update from 2.32 to 2.48 the system goes offline and no longer connects to the internet. It seems the containers start up because we do see status lights blinking consistent with the startup sequence of our containers, but the device never connects. The only thing that seems to solve it is a new SD card.
This is unfortunately a big problem for us because the systems in the field are difficult to get to, especially with covid-based movement restrictions. Previously, updating our images on 2.32 over low-bandwidth connections was unreliable, and the advice we received was to update to latest OS first.
Is there a best practice for upgrading that would minimize the chance of this happening? Is there any evidence that it would be more reliable if we went from 2.32 to an intermediary release, such as 2.44 and from there to 2.48? Given our poor <70% upgrade success rate, as is we have to write off OTA updates completely, which is a pretty big bummer.
