`malformed-deb-archive`

The binary package is not a correctly constructed archive. A binary Debian package must be an ar archive with exactly three members: debian-binary, control.tar.gz, and one of data.tar.gz, data.tar.bz2 or data.tar.xz (or data.tar.zst on Ubuntu) in exactly that order. The debian-binary member must start with a single line containing the version number, with a major revision of 2.
