Traceback (most recent call last):
  File "/usr/bin/lp-project-upload", line 175, in <module>
    main()
  File "/usr/bin/lp-project-upload", line 126, in main
    file_content = open(tarball, 'r').read()
  File "/usr/lib/python3.10/codecs.py", line 322, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)

From the traceback it looks like the failure is attempting to open/read the tarball.

I verified that the tarball is not corrupted by untaring it via `tar xvf <filename>`
