This problem occurs on a Debian install predominantly intended to follow the Stable release.
Some packages on the system need to be upgraded to Testing. A file has been added to /etc/apt/apt.conf.d called 88ccc $ cat /etc/apt/apt.conf.d/88ccc // APT::Default-Release "stable"; // And /etc/apt/sources.list set to: deb http://ftp.ca.debian.org/debian/ stable main contrib non-free #deb http://ftp.ca.debian.org/debian/ testing main contrib non-free deb http://security.debian.org/ stable/updates main contrib non-free #deb http://security.debian.org/ testing/updates main contrib non-free deb http://ftp.ca.debian.org/debian/ squeeze-updates main contrib non-free When the two testing lines in sources.list above are uncommented, a whole bunch of updates from testing show up when running: sudo apt-get upgrade I would have expected those packages to stay at the Stable release. Is this intended? Will some or all packages be upgraded to Testing regardless of the Default-Release setting? Thanks, Chris. $ sudo apt-config dump APT ""; APT::Architecture "i386"; APT::Build-Essential ""; APT::Build-Essential:: "build-essential"; APT::Install-Recommends "true"; APT::Install-Suggests "0"; APT::Authentication ""; APT::Authentication::TrustCDROM "true"; APT::NeverAutoRemove ""; APT::NeverAutoRemove:: "^firmware-linux.*"; APT::NeverAutoRemove:: "^linux-firmware$"; APT::NeverAutoRemove:: "^linux-image.*"; APT::NeverAutoRemove:: "^kfreebsd-image.*"; APT::NeverAutoRemove:: "^linux-restricted-modules.*"; APT::NeverAutoRemove:: "^linux-ubuntu-modules-.*"; APT::NeverAutoRemove:: "^gnumach$"; APT::NeverAutoRemove:: "^gnumach-image.*"; APT::Never-MarkAuto-Sections ""; APT::Never-MarkAuto-Sections:: "metapackages"; APT::Never-MarkAuto-Sections:: "restricted/metapackages"; APT::Never-MarkAuto-Sections:: "universe/metapackages"; APT::Never-MarkAuto-Sections:: "multiverse/metapackages"; APT::Never-MarkAuto-Sections:: "oldlibs"; APT::Never-MarkAuto-Sections:: "restricted/oldlibs"; APT::Never-MarkAuto-Sections:: "universe/oldlibs"; APT::Never-MarkAuto-Sections:: "multiverse/oldlibs"; APT::Periodic ""; APT::Periodic::Update-Package-Lists "1"; APT::Periodic::Download-Upgradeable-Packages "0"; APT::Periodic::AutocleanInterval "0"; APT::Update ""; APT::Update::Post-Invoke ""; APT::Update::Post-Invoke:: "touch /var/lib/apt/periodic/update-success-stamp 2>/dev/null || true"; APT::Archives ""; APT::Archives::MaxAge "30"; APT::Archives::MinAge "2"; APT::Archives::MaxSize "500"; APT::Default-Release "stable"; APT::Architectures ""; APT::Architectures:: "i386"; Dir "/"; Dir::State "var/lib/apt/"; Dir::State::lists "lists/"; Dir::State::cdroms "cdroms.list"; Dir::State::mirrors "mirrors/"; Dir::State::extended_states "extended_states"; Dir::State::status "/var/lib/dpkg/status"; Dir::Cache "var/cache/apt/"; Dir::Cache::archives "archives/"; Dir::Cache::srcpkgcache "srcpkgcache.bin"; Dir::Cache::pkgcache "pkgcache.bin"; Dir::Etc "etc/apt/"; Dir::Etc::sourcelist "sources.list"; Dir::Etc::sourceparts "sources.list.d"; Dir::Etc::vendorlist "vendors.list"; Dir::Etc::vendorparts "vendors.list.d"; Dir::Etc::main "apt.conf"; Dir::Etc::netrc "auth.conf"; Dir::Etc::parts "apt.conf.d"; Dir::Etc::preferences "preferences"; Dir::Etc::preferencesparts "preferences.d"; Dir::Etc::trusted "trusted.gpg"; Dir::Etc::trustedparts "trusted.gpg.d"; Dir::Bin ""; Dir::Bin::methods "/usr/lib/apt/methods"; Dir::Bin::dpkg "/usr/bin/dpkg"; Dir::Media ""; Dir::Media::MountPath "/media/apt"; Dir::Log "var/log/apt"; Dir::Log::Terminal "term.log"; Dir::Log::History "history.log"; Dir::Ignore-Files-Silently ""; Dir::Ignore-Files-Silently:: "~$"; Dir::Ignore-Files-Silently:: "\.disabled$"; Dir::Ignore-Files-Silently:: "\.bak$"; Dir::Ignore-Files-Silently:: "\.dpkg-[a-z]+$"; Acquire ""; Acquire::cdrom ""; Acquire::cdrom::mount "/media/cdrom/"; Acquire::Languages ""; Acquire::Languages:: "en_CA"; Acquire::Languages:: "en"; Acquire::Languages:: "none"; Unattended-Upgrade ""; Unattended-Upgrade::Origins-Pattern ""; Unattended-Upgrade::Origins-Pattern:: "origin=Debian,label=Debian-Security,archive=stable"; DPkg ""; DPkg::Pre-Install-Pkgs ""; DPkg::Pre-Install-Pkgs:: "/usr/sbin/dpkg-preconfigure --apt || true"; DPkg::Post-Invoke ""; DPkg::Post-Invoke:: "if [ -x /usr/bin/rkhunter ] && grep -qiE '^APT_AUTOGEN=.?(true|yes)' /etc/default/rkhunter; then /usr/share/rkhunter/scripts/rkhupd.sh; fi"; DPkg::Post-Invoke:: "if [ -d /var/lib/update-notifier ]; then touch /var/lib/update-notifier/dpkg-run-stamp; fi; if [ -e /var/lib/update-notifier/updates-available ]; then echo > /var/lib/update-notifier/updates-available; fi "; CommandLine ""; CommandLine::AsString "apt-config dump"; -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
