l'm trying to install Stata on a unix kernel (unbuntu 20.10) installed on WSL on Windows 10 and i get the following error. Any ideas on what I might be doing wrong?

Code:
  1.  uncompressing files

gzip: ado.tar.Z: not in gzip format

gzip: bins.tar.Z: not in gzip format

gzip: docs.tar.Z: not in gzip format
  2.  extracting files
tar: bins.tar: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
tar: ado.tar: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
tar: docs.tar: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
  3.  setting permissions
chmod: cannot access 'stinit': No such file or directory
chmod: cannot access 'docs': No such file or directory
chmod: cannot access 'docs/*.pdf': No such file or directory
chmod: cannot access 'docs/update': No such file or directory
find: ‘/usr/local/stata/ado’: No such file or directory
find: ‘/usr/local/stata/ado’: No such file or directory

Done.  The next step is to run the license installer.  Type:

        ./stinit

After that, you will be able to run Stata.  Look at your license.
If the licensed software is Stata/MP 16, you will be able to run
Stata/MP by typing
        xstata-mp           (Run windowed version of Stata/MP)
        stata-mp            (Run console  version of Stata/MP)

If the licensed software is Stata/SE 16, you will be able to run
Stata/SE by typing
        xstata-se           (Run windowed version of Stata/SE)
        stata-se            (Run console  version of Stata/SE)

If the licensed software is Stata/IC 16, you will be able to run
Stata/IC by typing
        xstata              (Run windowed version of Stata/IC)
        stata               (Run console  version of Stata/IC)

Make sure /usr/local/stata is in your Unix path.
Now run ./stinit
