Can you try next command?

sudo mount -o remount,size=1G /var/tmp

And then add image once again.

I had this same issue. Attempted to resize (to 400M) /var/tmp, and the system ran out of memory during download causing a crash. This particular VM only has 512MB of RAM.

1.3.3 does seem to be a bit larger than previous releases at 365 MiB.

[giga1699]

Upgrading VM to 1GB (which admittedly is the minimum recommended spec) gives the system 495M of /var/tmp space.

I was able to successfully update a test router from 1.3.2 to 1.3.3.

@echowings I would suggest you upgrade the RAM to 1GB minimum and you should see the space become available to download/install 1.3.3.
