I was unable to use lp-project-upload to upload a new release of safe-rm to
Launchpad:

  $ gpg --armor --sign --detach-sig safe-rm-0.13.tar.gz
  gpg: using "8C470B2A0B31568E110D432516281F2E007C98D1" as default secret key for signing
  $ lp-project-upload safe-rm 0.13 safe-rm-0.13.tar.gz
  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/python3.8/codecs.py", line 322, in decode
      (result, consumed) = self._buffer_decode(data, self.errors, final)
  UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8b in position 1: invalid start byte

Looks like it might be a bug introduced from the Python 2 conversion of the
code.

I just bumped into this. The solution is to open the release tarball and
its signature as binary, as follows. This should probably just be
squashed into debian/patches/02_python3:
