zlib error

[jay-goyal]

When I try to run jumpstart.sh, I get a huge error which I could not fix.

Traceback (most recent call last):
  File "/usr/lib/python3.8/site-packages/urllib3/response.py", line 399, in _decode
    data = self._decoder.decompress(data)
  File "/usr/lib/python3.8/site-packages/urllib3/response.py", line 86, in decompress
    ret += self._obj.decompress(data)
zlib.error: Error -3 while decompressing data: incorrect header check

During handling of the above exception, another exception occurred:

I could not fix this error but I got MacOS Catalina working through another fantastic tutorial... https://sick.codes/how-to-install-macos-virtual-machine-on-linux-arch-manjaro-catalina-mojave-or-high-sierra-xcode-working/ Here is the link... Also you might want to try a snap called Sosumi. It is based on the same project but since I am not going to install snapd on my install, I can't comment on if it will work.
