I was using KPackage, which I thought is a package manager like aptitude or synaptic. I need to try to keep up with the latest release of Cadabra, which is now on the Debian website in Sid. I tried to install the latest release straight from Sid, using Konqueror. Konqueror gives an option to open with KPackage, which I always select. Then attempting the install gives a list of dependency problems, so I tried upgrading to Squeeze versions where necessary, always using Konqueror and KPackage. This worked fine until I got to libc6, and apparently the lenny libc6 was uninstalled, then the squeeze upgrade was going to be installed, but the installation failed because libc-bin was not installed. Normally one would then just install libc-bin, but in this case, with Lenny libc6 uninstalled, and Squeeze libc6 installation failed, the result was that dpkg was broken. However I've now fixed the problem, as reported in another message. I guess the answer to this is that for system-critical packages, one should first do a "dry run" in KPackage, by clicking the "Test (do not install)" checkbox. But it would be really helpful if there was a list somewhere of the system-critical packages for which one needs to do this, to save having to do a dry run for every new package. I once made such a list for Etch, by searching for all the Essential and Required packages in the Etch Packages.gz. The list of the 61 Required packages for Etch, which I believe includes the 24 Essential packages at its start, is: tzdata libc6 bsdutils diff findutils grep hostname mktemp perl-base sed tar base-passwd mawk base-files libsepol1 libselinux1 sysvinit-utils libattr1 libacl1 coreutils debianutils dpkg gzip libncurses5 ncurses-base ncurses-bin bash libdevmapper1.02 libblkid1 libuuid1 mount e2fslibs libcomerr2 libss2 e2fsprogs sysv-rc lsb-base initscripts sysvinit libslang2 zlib1g util-linux libpam-runtime libpam0g libcap1 libdb4.3 libpam-modules login makedev passwd procps gcc-4.1-base libgcc1 libstdc++6 dselect liblocale-gettext-perl libtext-charwidth-perl libtext-iconv-perl libtext-wrapi18n-perl debconf-i18n debconf I have been referring to this old list while doing Lenny to Squeeze upgrades today. It would be really helpful if there were lists like this for Lenny and Squeeze somewhere on debian.org. Besides, it's nice to know what the Essential and Required packages are! I've learned today that when there are circular conflicts while upgrading, e.g. libcairo2 has to be upgraded to install xulrunner-1.9.1, but upgrading libcairo2 breaks xulrunner-1.9, it helps to use the dpkg --auto-deconfigure option before the -i action-parameter, e.g. dpkg --auto-deconfigure -i libcairo2_1.8.10-4_i386.deb Then dpkg gives a nice message about considering deconfiguration of xulrunner-1.9, then decides to do it, and it works, or at least, it has done, the two or three times I have tried it today.
