Package: synaptic Version: 0.84.2 Followup-For: Bug #276655 I have reported the bug #890668 about unattended-upgrades package In it's recent version (0.99), this package upgrade all Debian packages (not only security packages) even if they are blocked on Synaptic.
The maintainer of this package tells me to use : apt-mark hold <package name> to hold a package. I suggest to use this function on Synaptic -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: i386 (i686) Foreign Architectures: 64, x32, 32 Kernel: Linux 4.15.0-1-686-pae (SMP w/8 CPU cores) Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8), LANGUAGE=fr_FR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages synaptic depends on: ii hicolor-icon-theme 0.17-1 ii libapt-inst2.0 1.6~alpha7 ii libapt-pkg5.0 1.6~alpha7 ii libatk1.0-0 2.26.1-3 ii libc6 2.26-6 ii libcairo-gobject2 1.15.10-1 ii libcairo2 1.15.10-1 ii libept1.5.0 1.1+nmu3+b1 ii libgcc1 1:8-20180218-1 ii libgdk-pixbuf2.0-0 2.36.11-1 ii libglib2.0-0 2.54.3-2 ii libgnutls30 3.5.18-1 ii libgtk-3-0 3.22.28-1 ii libpango-1.0-0 1.40.14-1 ii libpangocairo-1.0-0 1.40.14-1 ii libpcre2-8-0 10.22-6 ii libstdc++6 8-20180218-1 ii libvte-2.91-0 0.50.2-4 ii libx11-6 2:1.6.4-3 ii libxapian30 1.4.5-1 ii policykit-1 0.105-18 ii zlib1g 1:1.2.8.dfsg-5 Versions of packages synaptic recommends: ii libgtk2-perl 2:1.24992-1+b1 ii rarian-compat 0.8.1-6+b1 ii xdg-utils 1.1.2-1 Versions of packages synaptic suggests: ii apt-xapian-index 0.49 ii deborphan 1.7.28.8-0.3+b1 pn dwww <none> ii menu 2.1.47+b1 ii software-properties-gtk 0.96.20.2-1 ii tasksel 3.43 -- no debconf information
