I had just under 2GB available on my 64GB card before the update. After the update it’s showing 0 available even though I haven’t used all the blocks. When typing “df” at the command line it shows this:
Filesystem 1k-blocks Used Available Use
/dev/root 59455228 57517592 0 100%
I thought it was maybe just a visual error but it won’t let me copy any new files since it thinks I’m out of space. If I delete a file the Available space still remains at 0, but the Used space will go down. When I take the sdcard out and plug it into my ubuntu machine it shows 1.86GB available on the card.
