Hello, it’s my first time processing maps on Webodm and from yesterday I got a message “Invalid zip file” finishing the Post Processing fase on Webodm. BTW I processed the files twice and I got the same error, all as default settings.
Do I need to install something else like zip or similar?
I attach an image…
Thanks you very much.
Best.

Hey @pemase 
check that you are enough free disk space. Perhaps you are running low?
I have about 25 gb free. Or how many space needs to create the zip file?
Thank you for answer 
Less than 25GB for ~300 images.
How are you running WebODM (docker, natively, etc.)?
Hello “pierotofy”, thank you for answer me.
Thank you for your advice, that was the problem. I increased to 300GB and the problem was solved.
I appreciate your help.
Best
Q: How are you running WebODM (docker, natively, etc.)?
Yes, I installed manually with docker, python, etc. under Ubuntu.

I’m actually seeing this myself now (Invalid zip file) a lot when I didn’t before (about 1 in every 2 jobs). I’m not running out of storage or RAM, I’m certain of that. If I restart the process from Orthophoto usually on the second time around the process completes successfully. There is nothing useful in the console - last line is “Compressing all.zip”.
The same thing just happened to me. I processed a known good dataset after upgrading to 9.0 and got the invalid zip file error. I ran again from orthophoto step and it finished properly.
Somebody should open a bug in Issues · OpenDroneMap/WebODM · GitHub so that we can keep better track of this (if it hasn’t already been opened).
