Package: apt Version: 1.4.8 Severity: normal File: apt-secure I have a file: based repository: deb file:/ usr/src/deb/
But apt-get update complains: W: The repository 'file: usr/src/deb/ Release' does not have a Release file. N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use. N: See apt-secure(8) manpage for repository creation and user configuration details. This is excessive. A local file based repository is not dangerous to use just because it doesn't have a Release file. Adding a release file will in no way secure it - anyone with access to change anything, can also change the Release file. -Ariel -- System Information: Debian Release: 9.5 APT prefers stable APT policy: (990, 'stable') Architecture: i386 (x86_64) Foreign Architectures: amd64 Kernel: Linux 4.9.110 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE= (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 2017.5 ii gpgv 2.1.18-8~deb9u2 ii init-system-helpers 1.48 ii libapt-pkg5.0 1.4.8 ii libc6 2.24-11+deb9u3 ii libgcc1 1:6.3.0-18+deb9u1 ii libstdc++6 6.3.0-18+deb9u1 Versions of packages apt recommends: ii gnupg 2.1.18-8~deb9u2 ii gnupg2 2.1.18-8~deb9u2 Versions of packages apt suggests: pn apt-doc <none> ii aptitude 0.8.7-1 ii dpkg-dev 1.18.25 ii powermgmt-base 1.31+nmu1 ii python-apt 1.4.0~beta3 ii synaptic 0.84.2 -- no debconf information
