When I upgrade an Android application from Google Play, it gets downloaded, then the upgrade stops with the message “Error: Insufficient storage available.”
Yet none of the partitions seem to be nearly full. The app is about 10MB, and I have about 100MB free on
/data. Here's the output of
Filesystem Size Used Free Blksize /dev 171M 32K 171M 4096 /mnt/asec 171M 0K 171M 4096 /mnt/obb 171M 0K 171M 4096 /cache 469M 2M 466M 4096 /efs 6M 3M 3M 4096 /system 503M 329M 174M 4096 /data 1007M 895M 112M 4096 /storage/sdcard0 13G 4G 8G 4096
This is happening on a rooted stock 4.1.2 image from Google.
I've read other questions on this site, such as Why can't I install apps when I have enough storage?, insufficient storage error while updating installed apps [duplicate], and others, but they all concern situations with only about 10–20MB free, whereas I have a 100MB safety margin. Unlike Something is secretly eating up my Acer Iconia A500 internal memory and I need help finding it and What can I do to manage my phone's internal storage?, I'm not trying to figure out which files are filling up a partition, I'm trying to figure out which partition is filled up.
So how can I figure out which partition this “insufficient storage” message is about?
/data/datadirectory that gave me headaches.
/data/datais on the same filesystem as
