Hi,

sorry for the late reply.
I assume that either the storage in your root partition or in /var/tmp is not sufficient.
If you upload a file it is first stored there (/var/tmp) and the moved to the final place.

Hope this helps

What is the exact error message?

Hmm. How do you fit a Ubuntu installation into 3 GB? Are you really referring to RAW format (i. e. a full-blown filesystem image), or is it a qcow2 image of (much) greater size?

In case it’s the latter, and the final size would be >59 GB, then you hit the same obstacle as me.

This works for me，thanks
