This evening's apt-get upgrade removed ubuntu-base and it won't reinstall. The problem seems to boil down to libc6-i686: PreDepends: libc6.1 (=2.3.2.ds1-20ubuntu12) but it is not installable Anyone else seeing this? How can I tell what I've installed (probably from universe) that depends on an earlier version of libc6? -Eamonn
