IHi,

I am trying to install the plugin on OctoPi Image. I keep getting the below errors:

Installing plugin "Polar Cloud" from https://github.com/markwal/OctoPrint-PolarCloud/archive/master.zip...

Any help would be appreciated. Thanks

Hmmm... I haven't seen that error before. It's having trouble installing Pillow due to a problem with zlib decompression... Oof.
