I tried installing games-server/ut2004-ded, but installation wouldn't continue because of the SHA256 checksum failing. The affected file is "dedicatedserver3339-bonuspack.zip", which I downloaded several times from different servers, always getting the same checksums. These checksums are listed in /usr/portage/games-server/ut2004-ded/Manifest: e31cdb4f1ecfd31e51b4caea76db4ea7b522a4ca (RMD160) e1eda562d99e66a7e5972f05bbf0de8733bf60c9 (SHA1) 0e5e77738c0069f213689b48f8c50a5676dc5ffe03169d4c721c2a99bcc1af0c (SHA256) The are the checksums that I get: e31cdb4f1ecfd31e51b4caea76db4ea7b522a4ca (RMD160) e1eda562d99e66a7e5972f05bbf0de8733bf60c9 (SHA1) b8fc94fc843483b18c225e100736d10cb2690ba8666d6abbb274ea6ad718b18e (SHA256) I assume that the SHA256 checksum in Portage was created with a broken version of Portage / pycrypto (see bug #164462). emerge --info: Portage 2.1.2.11 (hardened/x86/2.6, gcc-3.4.6, glibc-2.5-r4, 2.6.20-hardened-r6 i686) ================================================================= System uname: 2.6.20-hardened-r6 i686 Intel(R) Celeron(R) CPU 2.40GHz Gentoo Base System release 1.12.9 Timestamp of tree: Wed, 15 Aug 2007 16:50:01 +0000 dev-lang/python: 2.3.5-r3, 2.4.4-r4 dev-python/pycrypto: 2.0.1-r6 sys-apps/sandbox: 1.2.17 sys-devel/autoconf: 2.13, 2.61 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10 sys-devel/binutils: 2.17 sys-devel/gcc-config: 1.3.16 sys-devel/libtool: 1.5.23b virtual/os-headers: 2.6.21 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=pentium4 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/env.d /etc/gconf /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/terminfo" CXXFLAGS="-O2 -march=pentium4 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="distlocks metadata-transfer sandbox sfperms strict" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" LANG="de_DE@euro" LC_ALL="de_DE@euro" LINGUAS="de" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages --filter=H_**/files/digest-*" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="apache2 berkdb cracklib crypt dedicated gd hardened hardenedphp jpeg mailwrapper midi mysql nls nptl nptlonly pam pic png readline ssl tcpd urandom x86 xml xml2 xorg zlib" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mulaw multi null plug rate route share shm softvol" ELIBC="glibc" INPUT_DEVICES="mouse keyboard" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="de" USERLAND="GNU" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LDFLAGS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY
