I think you installed too many un-optified apps from the Extra-Devel. Therefore it eaten all of your rootfs space, which will lead to not enough space requires by the installation requirement. The root space is where the download check before it allowing to pass the check constraint.

You will need at minimum of 48MB free inside the rootfs.

Type: df -h

into command Xterminal and the top line should say rootfs and space used and available. and also %.

Disable the Extra-Devel and Extra-Testing will freeing up to 27MB of rootfs. Why?? Because the application manager caching all the applications lists into the tmp folder in rootfs. Disable them would lead to free some space require to update the OS OTA.


The Rootfs space is very limited and only 256MB large. So that is why we do not recommending anyone without good knowledge and understand of Linux and applications in Devel to download anything from Devel as recommendation. We usually warned them do not installed anything from Devel unless you know what you are doing, other wise it potentially can kill or corrupt your OS on the device and lead to many problems and instability.

Please read Wiki for more information on how to free your "rootfs" space, and if you still can't free up enough space to do OTA update then I would recommending you to do uninstalling the applications or a reflashing with the Flasher 3.5, tutorial is available on Wiki, also I would suggest you to Flash the eMMC as well, since you probably got too many unstable software (s) on it. It might lead to infinity loop.

Hope all the best.
