Pritunl Server Start Error

Whenever I try to start pritunl on my ubuntu vps, it gives me the following error before crashing. How do I fix this?

Traceback (most recent call last):
  File "/usr/lib/pritunl/bin/pritunl", line 33, in <module>
    sys.exit(load_entry_point('pritunl==1.30.3157.70', 'console_scripts', 'pritunl')())
  File "/usr/lib/pritunl/bin/pritunl", line 22, in importlib_load_entry_point
    for entry_point in distribution(dist_name).entry_points
  File "/usr/lib/python3.9/importlib/", line 524, in distribution
    return Distribution.from_name(distribution_name)
  File "/usr/lib/python3.9/importlib/", line 187, in from_name
    raise PackageNotFoundError(name)
importlib.metadata.PackageNotFoundError: pritunl

This is likely caused by configuring the wrong repository. Use the repository configuration for the correct Ubuntu version and reinstall the Pritunl package.

Even when I directly copy the provided script, I still receive the same error.

What Linux distribution and release is used?
