Source broken archive

Hi together,

after trying to build filezilla it appears that the upstream package source is broken and also the checksum has changed:

pkgctl build:

==> Retrieving sources...
  -> Found FileZilla_3.67.1_src.tar.xz
==> WARNING: Skipping all source file integrity checks.
==> Extracting sources...
==> Starting prepare()...
/startdir/PKGBUILD: line 32: cd: filezilla-3.67.1: No such file or directory
==> ERROR: A failure occurred in prepare().
    Aborting...
==> ERROR: Build failed, check /var/lib/archbuild/extra-x86_64/ptr1337-10/build

likely since the source was cached from archlinux side, the package were still possible to build.

extracting it:

tar xvzf FileZilla_3.67.1_src.tar.xz 

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
