Comment 0 for bug 1786111

On 1.0.9 (bionic-proposed, possibly also cosmic), ./fdroid signatures or ./fdroid signatures blabla.apk yields:
TypeError: extract() takes 1 positional argument but 2 were given.
This renders the command useless; it appears to be broken.

This is/was the upstream issue: https://gitlab.com/fdroid/fdroidserver/issues/536
The issue is fixed via this commit: https://gitlab.com/fdroid/fdroidserver/commit/d76c5dc859e2bfd7de9cbecd81bb68738858ed42
