Socket.timeout on upgrade

Getting this set of issues when attempting to upgrade from 0.33.3. Any ideas? I don’t have masses of free space, but should be enough to upgrade. I tried it a couple of times to be sure, but same message each time. My existing system is mostly working. Having some issues with emulated Hue. I was hoping there may be some fixes

Update: Still get this when trying to upgrade to 0.35

Cleaning up...
