status: ERROR: not enough disk space, 7.5MiB is required and only 7.4MiB is free
I experienced this particular problem myself on a hAP lite too. Just that tiny little free space I didnt have - despite I had no files on storage which I could remove to reclaim some space. I had to use netinstall back then. Tick “Keep configuration” and you’re pretty much good to go.
Devices with more RAM do have RAM-disk for this, but on these old 32MB-RAM devices this is not possible IIRC. So the update-package has to fit in flash.
I made the horrible mistake of upgrading from long-term to stable.
Remote downgrade fails.
It is not clear why netinstall should succeed, as the amount of free space does not change.
This is a device that was set aside for a manual downgrade to long-term stream via netboot. It was still connected to the network and thus cron catched it for regular updates. It is up and running. Should I expect it to malfunction and downgrade it anyway?
Netinstall should be the way out. Make sure to EXPORT config first so you can apply it again after netinstall (and make SURE your export is complete).
Don't use backup/restore or you will bring the problems simply back in.
Also, make a good assessment on what you have on that storage if it is really needed or not (in case other packages are loaded on that device).
Devices with less than 32MB storage and more than 64MB RAM will have RAM disk as their "storage root" (and actual permanent storage will be mapped under /flash ). So when you uploaded those 5MB worth of crap, it was uploaded onto RAM disk.
Other than that, Chateau will definitely struggle if one wants to have all the bells and whistles ... specially so if one attempts to install wifi-qcom-ac instead of wireless (the former makes device's wifi perform much better but also occupies quite a bit more flash space) ...
