"Short write" while updateing/upgradeing

Hi,

(yes, I made a backup of the SD card, which was delivered with the
beaglebone.. :slight_smile: :wink: )

After logging in into the beaglebone (root/serial console login) I did
a

    opkg update
    opkg upgrade

after a (longer) while every write was commented with a "short write"
message...

Is this the Beaglebones way to say "no space left on device" (I did
a "df -h" and found nothing, which shows a shortage of space...but
may be I overlooked something...)

What is the root of this evil ;)) ?

Best regards,
mcc
