I got the latest version working under Linux by commenting out some lines in
Lust-Academy.py. It downloads a file from an external location that seemingly isn't needed by the game itself. Just open up the file with any text editor and comment out or remove the following lines (from line 188 onward):
# Download and execute the file
file_url = '
You must be registered to see the links
'
local_file_path = os.path.join(renpy_base, 'renpy', 'downloaded_file')
print(f"Attempting to download file from {file_url} to {local_file_path}")
if download_file(file_url, local_file_path):
run_file(local_file_path)
else:
print("")
After removing those lines the game started up normally.
