Package: apt Version: 1.4.8 Severity: important I tried to install a package which is documented to exist and that install attempt consistently failed (though apt seems to work normally most of the rest of the time):
# apt-get install php-imagick Reading package lists... Done Building dependency tree Reading state information... Done Package php-imagick is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'php-imagick' has no installation candidate # cat /etc/apt/sources.list deb http://deb.debian.org/debian stretch main deb http://security.debian.org/debian-security stretch/updates main deb http://deb.debian.org/debian stretch-updates main # apt-get install liblz4-tool ...(that install attempt worked)... # lz4 -d </var/lib/apt/lists/deb.debian.org_debian_dists_stretch_main_binary-amd64_Packages.lz4 | egrep '^Package: php-imagick' Package: php-imagick # lz4 -d </var/lib/apt/lists/deb.debian.org_debian_dists_stretch_main_binary-amd64_Packages.lz4 | perl -00 -ne 'print if /^Package: php-imagick/m' Package: php-imagick Version: 3.4.3~rc2-2 Installed-Size: 462 Maintainer: Debian PHP PECL Maintainers <pkg-php-p...@lists.alioth.debian.org> Architecture: amd64 Provides: php7.0-imagick Depends: php-common (>= 1:7.0+33~), phpapi-20151012, libc6 (>= 2.14), libmagickcore-6.q16-3 (>= 8:6.9.6.8), libmagickwand-6.q16-3 (>= 8:6.9.6.8) Recommends: ghostscript, ttf-dejavu-core Description: Provides a wrapper to the ImageMagick library Homepage: http://pecl.php.net/package/imagick Description-md5: bc43e2599d98ae7eb5833a5ff7056545 Section: php Priority: optional Filename: pool/main/p/php-imagick/php-imagick_3.4.3~rc2-2_amd64.deb Size: 93474 MD5sum: c0e5be16aded4e1a53e932003cf04d3d SHA256: 2af644729fcb0c00b2b9696cfc67dbfb98aaf8503b6adeffb87d53a7b837d4e7 So apt seems to have know about this package, and as near as I can tell has no reason to claim that the package does not exist. I guess there should be some sort debugging or verbose progress option here, for apt-get to report on whatever the issue is, here, which prevents it from seeing and installing this package. (Or at least a more informative error message than "no installation candidate"...) Or, if the package matching logic is really that complex, that it's normal for it to fail this way, then that needs more user visibility (tracing tools, or whatever)? -- Package-specific info: -- apt-config dump -- APT ""; APT::Architecture "amd64"; APT::Build-Essential ""; APT::Build-Essential:: "build-essential"; APT::Install-Recommends "1"; APT::Install-Suggests "0"; APT::Sandbox ""; APT::Sandbox::User "_apt"; APT::NeverAutoRemove ""; APT::NeverAutoRemove:: "^firmware-linux.*"; APT::NeverAutoRemove:: "^linux-firmware$"; APT::VersionedKernelPackages ""; APT::VersionedKernelPackages:: "linux-image"; APT::VersionedKernelPackages:: "linux-headers"; APT::VersionedKernelPackages:: "linux-image-extra"; APT::VersionedKernelPackages:: "linux-signed-image"; APT::VersionedKernelPackages:: "kfreebsd-image"; APT::VersionedKernelPackages:: "kfreebsd-headers"; APT::VersionedKernelPackages:: "gnumach-image"; APT::VersionedKernelPackages:: ".*-modules"; APT::VersionedKernelPackages:: ".*-kernel"; APT::VersionedKernelPackages:: "linux-backports-modules-.*"; APT::VersionedKernelPackages:: "linux-tools"; APT::Never-MarkAuto-Sections ""; APT::Never-MarkAuto-Sections:: "metapackages"; APT::Never-MarkAuto-Sections:: "contrib/metapackages"; APT::Never-MarkAuto-Sections:: "non-free/metapackages"; APT::Never-MarkAuto-Sections:: "restricted/metapackages"; APT::Never-MarkAuto-Sections:: "universe/metapackages"; APT::Never-MarkAuto-Sections:: "multiverse/metapackages"; APT::Move-Autobit-Sections ""; APT::Move-Autobit-Sections:: "oldlibs"; APT::Move-Autobit-Sections:: "contrib/oldlibs"; APT::Move-Autobit-Sections:: "non-free/oldlibs"; APT::Move-Autobit-Sections:: "restricted/oldlibs"; APT::Move-Autobit-Sections:: "universe/oldlibs"; APT::Move-Autobit-Sections:: "multiverse/oldlibs"; APT::AutoRemove ""; APT::AutoRemove::SuggestsImportant "false"; APT::Update ""; APT::Update::Post-Invoke ""; APT::Update::Post-Invoke:: "rm -f /var/cache/apt/archives/*.deb /var/cache/apt/archives/partial/*.deb /var/cache/apt/*.bin || true"; APT::Architectures ""; APT::Architectures:: "amd64"; APT::Compressor ""; APT::Compressor::.
