Just saw this: Unpacking libghc-parsec3-doc (from .../libghc-parsec3-doc_3.1.3-2_all.deb) ... dpkg: error processing /var/cache/apt/archives/libghc-parsec3-doc_3.1.3-2_all.deb (--unpack): trying to overwrite '/usr/lib/ghc-doc/hoogle/parsec.txt', which is also in package libghc-parsec2-doc 2.1.0.1-7 Is it a known issue? I can't find any bug about, but maybe it's a known problem… If not, then a conflicts should be added, I think? iustin
