I have got a Samsung Galaxy Nexus with Ubuntu 13.10, a write protected flash installation (Not even password change seems to be possible.) My free space is 12.7 GB. "Last update 2000-01-01" seems to show that all previous attempts to update where unsuccessful. When I try to update with button "Check for updates" it tells me "Ubuntu phone, Version 31". The download seems to complete 100%. Then error message, something like,
Error 28: No more space left.
df -h shows more or less plenty of space left, except for,
- /android/cache used 100% of 426M,
- /android/system used 98% of 59M,
- /tmp used 87% of 347M.
(Update of individual apps has worked previously. Now double entries of apps appear in "Storage => Installed apps, by name".)
