Debian-based things are *supposed* to be infinitely upgradeable using apt-get or aptitude or whatever.

The problems you describe are, AFAICT, inherent in anything that uses shared libs. They're just more visible in *nix because many shared libs get upgraded regularly, and this upgrade process can break dependencies. This can even happen in Gentoo, which is why they invented the "revdep-rebuild" script. I don't know what the Debian equivalent of this is, but you might need to find out and run it. The programs that I have seen fail in this manner don't fail silently. They report "missing libfoo.1.2.3.so" errors to stderr, not to an X dialog, which can confuse people. "ldd fooprogram | grep 'not found' " can also tell you which libraries are missing from fooprogram if fooprogram isn't working. (The most annoying recent dependency problem I've had was when hplip wouldn't talk to an Ethernet-connected HP-3600, and gave completely bogus error messages. Turns out you need to build hplip with SNMP support for it to talk to Ethernet-connected printers. Oops.) --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
