Package: apt Version: 1.4~rc2 Severity: important Hello,
I found the Signed-By option in sources.list(5) and thought this would be useful to try. I set it up with a fingerprint of the key that signed a repository. I then did an 'apt update' (or 'apt-get update', I tried both) and things went well. Then I decided to try and flip some bits in the fingerprint and see what happened. Turns out that nothing happens, apt proceeded without any complaint whatsoever. :( The documentation reads: If the option is set, only the key(s) in this keyring or only the keys with these fingerprints are used for the apt-secure(8) verification of this repository. I also attempted a package installation and that didn't complain either. This is the format I used: deb http://deb.leap.se/debian sid main Signed-By: 2f483BbCE87BEE2F7DFE99661E34A1828E203901 (the key fingerprint there is incorrect). micah -- System Information: Debian Release: 9.0 APT prefers unstable APT policy: (500, 'unstable'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.9.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages apt depends on: ii adduser 3.115 ii debian-archive-keyring 2014.3 ii gpgv 2.1.18-6 ii init-system-helpers 1.47 ii libapt-pkg5.0 1.4~rc2 ii libc6 2.24-9 ii libgcc1 1:6.3.0-8 ii libstdc++6 6.3.0-8 Versions of packages apt recommends: ii gnupg 2.1.18-6 ii gnupg1 1.4.21-3 ii gnupg2 2.1.18-6 Versions of packages apt suggests: pn apt-doc <none> ii aptitude 0.8.5-1 ii dpkg-dev 1.18.22 ii powermgmt-base 1.31+nmu1 ii python-apt 1.4.0~beta2 -- no debconf information
