In a Ubuntu 20.04 system, I had to upgrade autoconf to 2.71, which then required upgrading automake to 1.16.5. I downloaded automake-1.16_1.16.5-1.3.debian.tar.xz but after uncompressing, it has no 'configure' file. The directory looks like:
README.Debian automake.docs automake.lintian-overrides automake.prerm copyright patches tests
automake.dirs automake.install automake.postinst changelog gbp.conf rules upstream
automake.doc-base automake.links automake.preinst control not-installed source watch
My question is how to upgrade automake to 1.16.5.
